chore(ci): tidy CI/dev infra — drop local-ci, lift migration rule, scope by galaxy.stack label

Five connected cleanups across the dev/CI infrastructure:

1. Drop tools/local-ci/. The standalone Gitea + act_runner stack was
   the legacy "offline workflow validator"; the per-stage CI gate now
   runs on gitea.lan and the directory was only retained as a
   fallback. Removing it leaves no operational dependency: backend,
   gateway, and game code have no references; documentation that
   pointed at it (CLAUDE.md, docs/ARCHITECTURE.md, ui/docs/testing.md,
   tools/dev-deploy/README.md, tools/local-dev/README.md) is updated
   in this same change. Historical "Verified on local-ci run N"
   markers in ui/PLAN.md are preserved unchanged.

2. Lift the pre-production single-migration rule. The rule forced
   every schema delta into 00001_init.sql and required a manual
   make clean-data wipe on every backward-incompatible change in
   tools/dev-deploy/. Future schema deltas now land as additive
   sequence-numbered files (00002_*.sql, …) that goose applies
   automatically on backend startup; 00001_init.sql becomes an
   immutable baseline. Authoring conventions live in
   backend/internal/postgres/migrations/README.md. The chain may be
   squashed back into a fresh 00001 as a deliberate one-time
   operation before the first production deployment.

3. Document the deployment cadence. The dev environment is
   single-tenant: pushes to feature/* run the test workflows
   (go-unit, ui-test, integration) only; dev-deploy.yaml fires on
   push to development. A workflow_dispatch override on
   dev-deploy.yaml lets a developer preview a feature branch on the
   shared dev environment before merge; the next merge into
   development overwrites the manual deploy idempotently.

4. Scope compose-managed resources by an explicit
   galaxy.stack=<local-dev|dev-deploy> label. Both compose files
   stamp the label on every service, network, and named volume.
   Makefiles in tools/local-dev/ and tools/dev-deploy/ filter their
   engine-cleanup operations by (stack-label AND engine OCI title)
   so they never touch unrelated workloads on the same daemon.
   dev-deploy.yaml gains a pre-`compose up` step that reaps stale
   exited/dead containers under the dev-deploy stack label.

5. Backend now stamps the same galaxy.stack=<value> label on every
   engine container it spawns, sourced from a new BACKEND_STACK_LABEL
   env var (empty → label not applied; legacy-safe). Both compose
   files set it to their stack name (local-dev / dev-deploy). The
   contract is recorded in docs/ARCHITECTURE.md under
   "Container labels". A package-level test in
   backend/internal/runtime exercises both the label-present and
   label-absent paths.

No tests intentionally regressed: go test ./backend/internal/{config,
runtime,dockerclient} is green, both compose files validate cleanly,
and the backend, gateway, and game modules all build.

-**While the platform is not yet in production, every schema change goes
-into the existing `00001_init.sql` file** rather than a new
-`00002_*`-prefixed file. The intent is to keep the schema in one
-canonical place so reviewers and developers do not have to reconstruct
-the latest shape from a chain of incremental migrations.
+- Each schema change is a new file with a monotonically increasing
+  numeric prefix and a snake-case slug:
+  `0000N_short_description.sql`. Reuse of a prefix is forbidden once
+  the file is merged.
+- `00001_init.sql` is the historical baseline. Treat it as immutable
+  history; do not edit it to land new schema. Squashing the chain back
+  into a fresh `00001` is reserved for the explicit pre-production
+  cut-over.
+- Every file MUST contain both an `-- +goose Up` and `-- +goose Down`
+  section, even if Down is a single `DROP …` for the same artefacts.
+  Down migrations are exercised by the schema test and serve as the
+  documented rollback path.
+- Destructive changes (dropping columns/tables, renaming with data
+  loss) MUST be split into at least two migrations so the chain stays
+  rollable forward and backward without coordinated code+schema
+  windows:
+  1. add the new shape, dual-write the data, leave the old shape in
+     place;
+  2. once all readers have switched, drop the old shape in a follow-up
+     migration.
+- Migrations are applied automatically on backend startup, so a fresh
+  push to `development` plus the `dev-deploy.yaml` workflow brings the
+  long-lived dev database up to head without manual intervention.
+  `make -C tools/dev-deploy clean-data` is only needed when a developer
+  deliberately wants a fresh database.
+- The integration harness (`backend/internal/postgres/migrations_test.go`)
+  spins up a disposable Postgres per run and asserts the final table
+  set. When a migration adds or removes tables, update the expected
+  list in the same patch.
 
-Operationally this means that pulling a branch with schema changes
-requires a fresh database — the only consumer today is local development
-and integration tests, both of which spin up disposable Postgres
-instances.
+## Pre-production squash

-> that point on every schema change must be a new migration file with a
-> monotonically increasing prefix, and `00001_init.sql` becomes
-> immutable history.
-
-If you need to make a change, edit `00001_init.sql` directly. Down
-migrations should still be kept in sync (they live at the bottom of the
-file — currently a single `DROP SCHEMA backend CASCADE`).
+The chain may be squashed back into one clean `00001_init.sql` before
+the first production deployment. That is a deliberate, one-time
+operation; until then, additive numbered files are the rule. After the
+squash this file gets a short note that `00001_init.sql` represents
+the production baseline and the policy above continues to apply for
+every later migration.

 ## Persistent state and schema changes
 
 The dev Postgres volume `galaxy-dev-postgres-data` survives redeploys.
-Until the pre-production migration rule is lifted, every
-backward-incompatible change to `backend/internal/postgres/migrations/00001_init.sql`
-needs a manual wipe before the next deploy succeeds:
+Schema deltas land as additive, sequence-numbered migration files
+(`backend/internal/postgres/migrations/0000N_*.sql`) and `pressly/goose`
+applies them on backend startup without operator action.

+Use `make -C tools/dev-deploy clean-data` only when you deliberately
+want a fresh database (debugging schema drift, exercising the
+bootstrap path from scratch, etc.):
 
 ```sh
 make -C tools/dev-deploy clean-data
 make -C tools/dev-deploy up
 ```
 
-This is the same caveat as `tools/local-dev/`, just with a different
-volume name.
+The same volume-persistence model applies to `tools/local-dev/`.

 in the long-lived dev environment but are not yet fixed (currently:
 the sandbox game flipping to `cancelled` after a redispatch).
 
+## Deployment cadence
+
+This environment is single-tenant: one live deployment, redeployed by
+the `dev-deploy.yaml` workflow on every merge into `development`. PR
+branches do not auto-deploy here — pushes to `feature/*` only run the
+test workflows (`go-unit`, `ui-test`, `integration`).
+
+To put a feature branch on the shared dev environment before its PR
+merges (e.g. to validate a UI flow against the real Caddy edge), run
+the workflow manually:
+
+1. Push the branch (`git push gitea HEAD`).
+2. Gitea UI → **Actions → Deploy · Dev → Run workflow**, pick the
+   feature ref.
+
+The deploy is idempotent — when the PR later merges into
+`development`, the regular push trigger fires the same packaging and
+healthcheck steps, overwriting whatever the manual dispatch left
+behind. There is no separate state to clean up between the two paths.
+
 ## Relationship to other infrastructure
 
 - `tools/local-dev/` — single-developer playground, host-port mapped,
   Vite dev server on the side. Recommended for active UI work.
-- `tools/local-ci/` — Gitea + act runner for **fallback** workflow
-  testing without `gitea.lan`. Optional, not part of the per-stage CI
-  gate anymore.
 - `.gitea/workflows/dev-deploy.yaml` — the CI side of this stack:
   builds images, seeds the UI volume, runs `docker compose up -d` on
   every merge into `development`. The Makefile in this directory is

-# Local Gitea CI (fallback)
-
-> **Status:** fallback / opt-in. The primary CI target is now
-> `gitea.lan` with its host-mode `act_runner`. The per-stage CI gate
-> closes against `gitea.lan`, not against this stack. Use this
-> directory when you want to validate `.gitea/workflows/*` without
-> reaching `gitea.lan` — for example, when iterating on a workflow
-> file from a flight without LAN access — or when isolating a runner
-> issue from production-shaped infrastructure.
-
-Self-contained Gitea + Actions runner for verifying
-`.gitea/workflows/*` honestly before pushing to `gitea.lan`. Runs
-natively on arm64 (Apple Silicon) — every image below has an arm64
-variant, so Docker pulls the right architecture and the runner
-executes workflow steps without QEMU emulation.
-
-## Prerequisites
-
-- Docker (Colima or Docker Desktop)
-- `python3`, `curl`, `bash` — all built into macOS
-
-## First time
-
-```sh
-make -C tools/local-ci up
-```
-
-This:
-
-1. brings up the Gitea container;
-2. creates an admin user (`galaxy` / `galaxy-dev`);
-3. creates the `galaxy/galaxy` repo;
-4. fetches a runner registration token from the Gitea API;
-5. brings up the runner with that token (the runner persists its
-   credentials in a Docker volume and ignores the token on subsequent
-   restarts).
-
-The script is idempotent — re-running it is safe.
-
-## Pushing a branch
-
-```sh
-make -C tools/local-ci push
-```
-
-This adds a `local-gitea` remote on the first run and then pushes the
-current `HEAD`. Equivalent manual flow:
-
-```sh
-git remote add local-gitea \
-    http://galaxy:galaxy-dev@localhost:3000/galaxy/galaxy.git
-git push local-gitea HEAD
-```
-
-The Tier 1 workflow fires on `push` to any branch and the Tier 2
-workflow fires on tags matching `v*`. Watch runs at:
-
-<http://localhost:3000/galaxy/galaxy/actions>
-
-## Operational targets
-
-| Target           | What it does                                 |
-| ---------------- | -------------------------------------------- |
-| `make up`        | Bring up Gitea + runner (idempotent)         |
-| `make down`      | Stop both containers (state preserved)       |
-| `make logs`      | Tail logs from both containers               |
-| `make status`    | Show container status                        |
-| `make push`      | Push current `HEAD` to local Gitea           |
-| `make clean`     | Stop and wipe all local state (full reset)   |
-
-## What's in the box
-
-| Component  | Image                              | Role                                        |
-| ---------- | ---------------------------------- | ------------------------------------------- |
-| Gitea      | `gitea/gitea:1.23`                 | Server with SQLite backend                  |
-| act_runner | `gitea/act_runner:0.6.1`           | Single-capacity runner registered on boot   |
-| Workflow   | `catthehacker/ubuntu:act-latest`   | Image spawned per job (multi-arch)          |
-
-The runner mounts the host Docker socket and spawns workflow
-containers on the same Docker network as Gitea, so
-`actions/checkout` reaches the server at `http://gitea:3000` from
-inside spawned containers.
-
-## Caveats
-
-- Gitea's `ROOT_URL` is set to `http://gitea:3000/` so spawned
-  workflow containers reach the server through the compose network.
-  The web UI works at `http://localhost:3000` via port mapping, but
-  copy-paste URLs in the UI may show `gitea:3000` instead of
-  `localhost:3000`. Harmless for local dev; switch the host part by
-  hand when copying.
-- The runner is single-capacity (`runner.capacity: 1` in
-  `config.yaml`). Concurrent jobs queue. Bump if you need parallel
-  jobs.
-- First push from a fresh checkout uploads the full repo history
-  (~tens of MB). Subsequent pushes are deltas.
-- `actions/upload-artifact@v4` requires Gitea ≥ 1.21 — we pin
-  `1.23` to stay above the cutoff.
-- Workflow steps run as `root` inside the spawned container; this
-  matches the upstream catthehacker behaviour. Keep that in mind if
-  you add steps that touch host-mounted directories.
-- On Apple Silicon the runner image and its catthehacker child run
-  natively as arm64. Some pre-built tools that ship in the image are
-  amd64-only and would fall back to QEMU; `setup-go`, `setup-node`,
-  and `pnpm/action-setup` all download arm64 binaries themselves, so
-  the workflow steps we care about stay native.

-`tools/local-ci/` ships a self-contained Gitea + Actions runner via
-docker-compose so workflow changes are exercised end-to-end on a real
-runner before pushing to a remote Gitea instance. On Apple Silicon
-the runner and every spawned workflow container are arm64-native
-(no QEMU). Full runbook lives in
-[`../../tools/local-ci/README.md`](../../tools/local-ci/README.md);
-the cheat sheet below covers the operations needed when working a
-phase that touches CI.
+Workflow changes are exercised on the primary CI host (`gitea.lan`).
+Push the branch (`git push gitea …`), then open the run in the Gitea
+UI to inspect the status and logs. See `CLAUDE.md` (`## Per-stage CI
+gate`) for the per-stage workflow.

-
-### Inspect a run from the shell
-
-The Gitea Actions API is on `http://localhost:3000/api/v1` with basic
-auth. Useful for verifying a workflow change without opening the
-browser:
-
-```sh
-# Latest workflow runs — `status` is a human-readable string here:
-# "running" / "success" / "failure" / "cancelled".
-curl -s -u galaxy:galaxy-dev \
-  'http://localhost:3000/api/v1/repos/galaxy/galaxy/actions/tasks?limit=5' \
-  | python3 -m json.tool
-
-# Tight one-liner for the latest run only:
-curl -s -u galaxy:galaxy-dev \
-  'http://localhost:3000/api/v1/repos/galaxy/galaxy/actions/tasks?limit=1' \
-  | python3 -c 'import json, sys; r=json.load(sys.stdin)["workflow_runs"][0]; print(r["run_number"], r["status"], r["display_title"])'
-```
-
-Step-by-step workflow output is stored zstd-compressed under
-`/data/gitea/actions_log/galaxy/galaxy/<run_padded>/<job_index>.log.zst`
-inside the gitea container:
-
-```sh
-docker compose -f tools/local-ci/docker-compose.yml exec -T gitea sh -c '
-  apk add --quiet zstd
-  zstdcat /data/gitea/actions_log/galaxy/galaxy/01/1.log.zst
-' | less
-```
-
-`<run_padded>` is the run number, zero-padded to two digits
-(`01`, `02`, …); `<job_index>` is the 1-based index of the job
-inside that run (only `1` for the current single-job workflows).
-
-### Typical phase workflow
-
-When a phase changes anything under `.gitea/workflows/` or surfaces
-new tests in CI:
-
-1. Local sanity first — run the affected commands directly
-   (`pnpm test`, `pnpm exec playwright test`, the targeted
-   `go test ./...` slice).
-2. Commit and `make -C tools/local-ci push`.
-3. Poll the API for the latest run; once it leaves `running`,
-   inspect status. On failure pull the log via the snippet above.
-4. Fix and repeat. The runner is always-on; each push triggers a
-   fresh run (test cache is cleared by `-count=1` so a green run is
-   honest).
