fix: address ultrareview findings across backend and frontend
Backend:
- rate-limiter: retryAfter now in seconds; ms-precision lu preserves
fractional regen residue across calls (C1, C2)
- redis-client: throw on Upstash 200-with-error envelope; redisRaw
returns body.result (NH1)
- constants: MAX_BATCH_SIZE = MAX_CREDITS = 256 (was 512 vs 256)
- worker: content-length cap, gzip + s-maxage=10 on /api/canvas,
broadcast via executionCtx.waitUntil with r.ok check (NC2, H4, H5)
- canvas-storage: warn on truncated Upstash read instead of silent
zero-pad (NH2)
- get-user-id: SHA-256 (16 hex chars) replaces 32-bit string hash;
missing cf-connecting-ip routes to anon:dev with warn (H1, H2);
function is now async
- canvas-room: log unclean WS closes and errors; defensive close on
unexpected client message (NH4, N5)
Frontend:
- pixel buffer capped at MAX_BATCH_SIZE with toast (NC2)
- Submit error UX: toast for 429/413/400/5xx/network; honor
retryAfter (NC1)
- committedColors allocated upfront so WS updates during initial
fetch no longer null-deref (NC3)
- handleWheel always renders even when zoom is clamped (C1, C2)
- canvas-decoder throws on truncated input instead of reading past
end with || 0 (C3)
- WS reconnect refetches canvas to recover missed pixels (C4)
- pixel-buffer Map cache for O(1) getColorAt/pixelCount (NH1)
- cancel in-progress stroke on mode switch (NH3)
- canvas load error overlay with Retry button (NH5)
- DPR-aware canvas sizing (H1)
- onMount cleanup is now sync (no leaked resize listener) (H2)
Tests:
- update for async getUserId, decoder bounds check, redis error
format; add Upstash error-envelope coverage

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.
