feat(canvas): migrate canvas + cooldown storage to DO SQLite

Move pixel state and rate-limit cooldowns out of Upstash Redis and into
the existing CanvasRoom Durable Object's SQLite-backed storage. Worker
becomes a thin validation/proxy; the DO does atomic cooldown check +
pixel write + WS broadcast in one in-memory step.

Why: eliminate external dependency, keep $0/month free-tier forever,
exploit single-threaded actor for strong consistency without round-trips.

Architecture:
- canvas_chunks: 256 BLOB rows × 64 KB; CHUNK_COUNT derived from
  CANVAS_WIDTH × CANVAS_HEIGHT / CHUNK_BYTES so resize is config-only.
- cooldowns: user_id → expires_at, 1% sample-rate lazy GC.
- Worker forwards /api/canvas, /api/place, /api/ws to DO endpoints.
- POST /admin/migrate-from-upstash: token-gated one-shot importer.

Phases 1-3 code complete; Upstash dependency stays until prod migration
runs and 7-day rollback window passes (Phase 4).

Plan: plans/260509-2309-canvas-on-do-storage/

refactor(rate-limit): 1 req/sec cooldown, batch up to 2048 (#3 )

* refactor(rate-limit): switch to 1 req/sec cooldown, batch size up to 2048

Replace per-pixel credit/token-bucket model with a simple per-user cooldown
(SET NX EX 1). Batch size is now independent of the rate limit and capped
at MAX_BATCH_SIZE = 2048.

- rate-limiter: SET NX EX replaces Lua credit script
- worker: response shape { ok: true } (no credits field)
- client: drop credit state/timer/UserInfo; uploader paces by cooldown
- tests: mock checkRateLimit; integration test exercises SET NX EX
- docs: README, system-architecture, code-standards, deployment-guide

* chore(plans): remove implemented plan directories

rplace-implementation (base build), review-fixes, and
image-importer-enhancements are all shipped. Keep plans/reports/ as
historical code-review and research references.

test: add comprehensive unit tests with Vitest

65 tests covering canvas decoder, pixel buffer, user ID hashing,
canvas storage (with binary encoding regression test), Redis client
API shape, and worker endpoint validation.
