ui/phase-11: map wired to live game state

Replaces the Phase 10 map stub with live planet rendering driven by
`user.games.report`, and wires the header turn counter to the same
data. Phase 11's frontend sits on a per-game `GameStateStore` that
lives in `lib/game-state.svelte.ts`: the in-game shell layout
instantiates one per game, exposes it through Svelte context, and
disposes it on remount. The store discovers the game's current turn
through `lobby.my.games.list`, fetches the matching report, and
exposes a TS-friendly snapshot to the header turn counter, the map
view, and the inspector / order / calculator tabs that later phases
will plug onto the same instance.

The pipeline forced one cross-stage decision: the user surface needs
the current turn number to know which report to fetch, but
`GameSummary` did not expose it. Phase 11 extends the lobby
catalogue (FB schema, transcoder, Go model, backend
gameSummaryWire, gateway decoders, openapi, TS bindings,
api/lobby.ts) with `current_turn:int32`. The data was already
tracked in backend's `RuntimeSnapshot.CurrentTurn`; surfacing it is
a wire change only. Two alternatives were rejected: a brand-new
`user.games.state` message (full wire-flow for one field) and
hard-coding `turn=0` (works for the dev sandbox, which never
advances past zero, but renders the initial state for any real
game). The change crosses Phase 8's already-shipped catalogue per
the project's "decisions baked back into the live plan" rule —
existing tests and fixtures are updated in the same patch.

The state binding lives in `map/state-binding.ts::reportToWorld`:
one Point primitive per planet across all four kinds (local /
other / uninhabited / unidentified) with distinct fill colours,
fill alphas, and point radii so the user can tell them apart at a
glance. The planet engine number is reused as the primitive id so
a hit-test result resolves directly to a planet without an extra
lookup table. Zero-planet reports yield a well-formed empty world;
malformed dimensions fall back to 1×1 so a bad report cannot crash
the renderer.

The map view's mount effect creates the renderer once and skips
re-mount on no-op refreshes (same turn, same wrap mode); a turn
change or wrap-mode flip disposes and recreates it. The renderer's
external API does not yet expose `setWorld`; Phase 24 / 34 will
extract it once high-frequency updates land. The store installs a
`visibilitychange` listener that calls `refresh()` when the tab
regains focus.

Wrap-mode preference uses `Cache` namespace `game-prefs`, key
`<gameId>/wrap-mode`, default `torus`. Phase 11 reads through
`store.wrapMode`; Phase 29 wires the toggle UI on top of
`setWrapMode`.

Tests: Vitest unit coverage for `reportToWorld` (every kind,
ids, styling, empty / zero-dimension edges, priority order) and
for the store lifecycle (init success, missing-membership error,
forbidden-result error, `setTurn`, wrap-mode persistence across
instances, `failBootstrap`). Playwright e2e mocks the gateway for
`lobby.my.games.list` and `user.games.report` and asserts the
live data path: turn counter shows the reported turn,
`active-view-map` flips to `data-status="ready"`, and
`data-planet-count` matches the fixture count. The zero-planet
regression and the missing-membership error path are covered.

Phase 11 status stays `pending` in `ui/PLAN.md` until the local-ci
run lands green; flipping to `done` follows in the next commit per
the per-stage CI gate in `CLAUDE.md`.

-- `ui/frontend/src/lib/header/turn-counter.svelte` reads the live
-  turn number from game state
+1. **`current_turn` on `GameSummary`.** The user-facing
+   `lobby.my.games.list` did not expose the runtime's current turn
+   number, but the in-game shell needs it to fetch the matching
+   `user.games.report`. Phase 11 extends `GameSummary` with a new
+   `current_turn:int32` field (FB schema, Go transcoder + model,
+   backend `gameSummaryWire`, gateway `decodeGameSummary*`,
+   `backend/openapi.yaml`, TS bindings, `api/lobby.ts`). The data
+   was already tracked in the runtime projection
+   (`backend/internal/lobby/types.go RuntimeSnapshot.CurrentTurn`);
+   exposing it is purely a wire change. Two alternatives were
+   rejected: a brand-new `user.games.state` message (full wire-flow
+   for a one-field response) and hard-coding `turn=0` (works for the
+   dev sandbox, but renders the initial state for any game past
+   turn zero). The decision crosses Phase 8's already-shipped
+   catalogue per the project's "decisions baked back into the live
+   plan" rule.
+2. **Per-game state store with context.** A `GameStateStore` lives
+   in `lib/game-state.svelte.ts`; the in-game shell layout
+   instantiates one per game and exposes it through Svelte context
+   under `GAME_STATE_CONTEXT_KEY`. Header turn counter, map view,
+   and (in later phases) inspector tabs all consume the same
+   instance. A new instance is created on layout remount (game id
+   change), so each game gets a fresh snapshot.
+3. **Lobby lookup for current turn.** The store does not assume the
+   caller passed `current_turn` through navigation state. On
+   `setGame`, it calls `lobby.my.games.list` itself, finds the game
+   record, reads `current_turn`, and then calls
+   `user.games.report`. A direct deep link to `/games/:id/map` for
+   a game the user is not a member of flips the store to `error`
+   with a `not in your list` message.
+4. **Refresh on tab focus.** The store installs a
+   `visibilitychange` listener that calls `refresh()` when the
+   document becomes visible and the store is `ready`. The map
+   view's mount effect skips a re-render when the new snapshot's
+   turn matches the previously-mounted turn (and the wrap mode is
+   unchanged), so a no-op refresh does not flicker the canvas.
+5. **Wrap-mode preference.** `Cache` namespace `game-prefs`, key
+   `<gameId>/wrap-mode`, values `torus` (default) / `no-wrap`.
+   Phase 11 reads through `wrapMode`; `setWrapMode` writes back.
+   Phase 29 wires the toggle UI on top of these primitives.
+6. **State binding.** `map/state-binding.ts::reportToWorld` emits
+   one Point primitive per planet across all four kinds (local /
+   other / uninhabited / unidentified) with distinct fill colours
+   and point radii. Each primitive's id reuses the engine planet
+   number so a hit-test result resolves directly to a planet
+   without an extra lookup table. Zero-planet reports yield a
+   well-formed empty world; the World constructor's positivity
+   check is guarded by a 1×1 fallback for the malformed-report
+   edge case.
+7. **Renderer remount on snapshot change.** The map view disposes
+   and recreates the renderer when the report's turn changes (and
+   short-circuits when it does not). This is wasteful for the
+   tab-focus refresh path, but the renderer's external
+   `RendererHandle` does not yet expose a `setWorld` API and Phase
+   11's per-game planet count is small enough that the remount
+   cost (a few hundred ms) is acceptable. A future phase that adds
+   high-frequency updates (Phase 24 push events, Phase 34 multi-
+   turn projection overlays) will extract a `replaceWorld` method.
+8. **e2e bootstrap reuses `__galaxyDebug`.** The Phase 10 pattern
+   of seeding the device session through `/__debug/store` carries
+   over; the gateway is mocked through `page.route` for
+   `lobby.my.games.list`, `user.games.report`, and the
+   `SubscribeEvents` stream that the revocation watcher opens
+   (held open indefinitely so a clean end-of-stream does not
+   trigger `signOut("revoked")` and bounce the test back to
+   `/login`).

+per game (the layout remounts when the user navigates to a different
+game id, so each game gets a fresh store). The layout exposes the
+instance through Svelte context under `GAME_STATE_CONTEXT_KEY`;
+descendants read it via `getContext(GAME_STATE_CONTEXT_KEY)`.
+
+The layout's `onMount` builds the `GalaxyClient`, loads `Cache`
+through `loadStore()`, then calls `gameState.init({ client, cache,
+gameId })`. `init`:
+
+1. installs a `visibilitychange` listener on `document` so the report
+   is refreshed when the tab regains focus;
+2. calls `setGame(gameId)`, which:
+   - reads the per-game wrap-mode preference from `Cache`
+     (`game-prefs / <gameId>/wrap-mode`, default `torus`);
+   - calls `lobby.my.games.list` and finds the game record (the
+     Phase 11 wire schema extension on `GameSummary` adds
+     `current_turn`); if the user is not a member, the store flips
+     to `error`;
+   - calls `user.games.report` for the discovered turn and decodes
+     the FlatBuffers response into a TS-friendly `GameReport` shape.
+
+The store exposes:
+
+| field         | type                          | meaning                                              |
+| ------------- | ----------------------------- | ---------------------------------------------------- |
+| `gameId`      | `string`                      | active game id                                       |
+| `status`      | `idle / loading / ready / error` | current lifecycle state                            |
+| `report`      | `GameReport \| null`          | latest decoded report, `null` until first fetch      |
+| `wrapMode`    | `torus / no-wrap`             | per-game preference, persisted via `Cache`           |
+| `error`       | `string \| null`              | localised error message when `status === "error"`    |
+
+## Phase boundaries
+
+- Phase 11 surfaces only the planet subset of the report. Later
+  phases extend `GameReport` and `decodeReport` as their slice of
+  the wire lands (ships, fleets, sciences, routes, battles, mail).
+- Phase 26 wires history mode through `setTurn(turn)`. The store
+  already supports it; the navigator UI is what is missing.
+- Phase 24 replaces the tab-focus refresh with push-event-driven
+  refreshes; the visibility listener stays as a fallback for
+  background tabs that miss a push.
+- Phase 29 wires the wrap-mode toggle UI on top of `setWrapMode`.
+
+## Why `current_turn` lives on `GameSummary`
+
+The user-facing surface needs the current turn number to know which
+report to fetch. Two alternatives were rejected:
+
+- a brand-new `user.games.state` message — adds a full wire-flow
+  (fbs schema, transcoder, gateway routing, backend handler) for a
+  one-field response;
+- hard-coding `turn=0` for all games — works for the dev sandbox
+  (which never advances past turn zero) but renders the initial
+  state for any real game past turn zero.
+
+Extending `GameSummary` reuses the existing lobby pipeline; the
+backend already tracks `current_turn` in its runtime projection
+(`backend/internal/server/handlers_user_lobby_helpers.go`
+`gameSummaryToWire` reads it from `g.RuntimeSnapshot.CurrentTurn`).
+
+The wire change touches Phase 8's already-shipped catalogue, but the
+`current_turn` field defaults to zero on the FB side, so existing
+tests and the dev sandbox flow continue to work unchanged.
+
+## State binding
+
+`map/state-binding.ts::reportToWorld(report)` translates a
+`GameReport` into a renderer-ready `World`. Phase 11 emits one Point
+primitive per planet across all four kinds (local / other /
+uninhabited / unidentified). Each kind gets a distinct fill colour,
+fill alpha, and point radius so the four classes are
+visually-distinguishable at a glance; later phases will refine the
+colour palette as the visual language stabilises (Phase 35 polish).
+
+The planet engine number is reused as the primitive id so a hit-test
+result can resolve back to a planet without an extra lookup table.
+
+## Refresh discipline
+
+`refresh()` re-fetches the same turn snapshot. It is called by the
+`visibilitychange` handler when `document.visibilityState ===
+"visible"` and the store is already in `ready` state. The map view's
+mount effect skips a re-render when the new snapshot's turn matches
+the previously-mounted turn (and the wrap mode is unchanged), so a
+no-op refresh does not flicker the canvas.
+
+`setTurn(turn)` is the entry point for Phase 26 history mode:
+calling it on a different turn loads that snapshot and the same
+mount effect re-creates the renderer with the new world.
+
+`setWrapMode(mode)` writes to `Cache` and updates the rune; the
+map view's effect picks the change up and re-mounts the renderer
+with the new mode.
