Follow-up tidy after the cross-service /command removal (#73):
- Rename the router test double dummyExecutor -> fakeEngine (and the
newExecutor / setupRouterExecutor helpers -> newFakeEngine /
setupRouterEngine): it implements handler.Engine now, "executor" was a
leftover of the removed adapter. Test-only.
- Regenerate the ui/core canon signing golden onto user.games.order
(request_user_games_command.json -> request_user_games_order.json, fresh
canonical bytes + Ed25519 signature) and drop the last
user.games.command references from the Go/TS tests and docs.
- Align game openapi: CommandRequest.cmd no longer carries minItems: 1. It
is now used only by PUT /api/v1/order, which accepts an empty batch
(clearing the player's stored order, equivalent to removing every
command); the contract test freezes the empty-allowed shape.

Validation of a player's order now applies every command against a
transient game-state snapshot and records the per-command outcome
(cmdApplied, cmdErrorCode) in each command's meta. The order is
persisted even when some commands are rejected, and the response is
202 + UserGamesOrder so clients can surface the partial failure
without the chain collapsing into "downstream service is unavailable".
Pkg/error consts are reshelved onto three explicit ranges with a
package doc and helpers (IsInternalCode/IsInputCode/IsGameStateCode):
1xxx internal/server (500/501), 2xxx structural input (400), 3xxx
game-state per-command rejection (400 when escaping HTTP, otherwise
recorded as cmdErrorCode). Two pre-existing typos fixed mechanically
(ErrBeakGroupNumberNotEnough -> ErrBreakGroupNumberNotEnough,
ErrRaceExinct -> ErrRaceExtinct) along with all callsites.
Engine errorResponse maps *GenericError by shelf rather than mapping
everything to 500. The Quit-not-last structural check in
Controller.ValidateOrder is preserved and its type assertion fixed
(was a value assertion against a pointer-typed command, so the check
silently never fired).
Backend, gateway and UI are unchanged — they were already correct on
the 202 path; only the engine collapsing per-command rejection into
500 was needed.

Replaces the manual Submit button with an auto-sync pipeline driven
by `OrderDraftStore`: every successful add / remove / move
coalesces a `submitOrder` call so the engine always mirrors the
local draft. Removing the last command sends an empty cmd[] PUT —
the engine, repo, and rest model now accept that as a valid
"player cleared their draft" state.
`hydrateFromServer` is now invoked unconditionally on game boot so
a fresh device picks up the player's stored order, and the local
cache is overwritten by the server's view (server is the source of
truth).
Header replaces the static "race ?" + turn counter with a single
headline string `<race> @ <game>, turn <n>`, sourced from the
engine's Report.race + the lobby's GameSummary.gameName + the live
turn number, with a `?` fallback while any piece is loading.
Tests:
- engine: empty PUT round-trips, repo round-trips empty Commands
- order-draft: auto-sync sends full draft on every mutation,
rejected response surfaces error sync status, rapid mutations
coalesce, server hydration overwrites cache
- order-tab: per-row status flips through the auto-sync lifecycle,
remove → empty cmd[] PUT, rejected → retry button
- inspector overlay: applied + valid + submitting all participate
in the optimistic projection
- header: live race / game / turn rendering with fall-back
