louis-cai ac98dd9d32 fix(antigravity): strike-break optimistic quota readings that keep 429ing
Google's quota API can report remaining quota while generation endpoints
keep returning 429 (sprint/weekly dual-pool mismatch). handleAntigravityQuotaError
trusted remainingPercentage > 0 as healthy and returned null, causing 429 retry
loops across multi-account pools.

Add a strike-based circuit breaker to the optimistic and unavailable quota paths:
- After 3 strikes (429/409) within 60s for the same connection+model, cache-block
  that pair for 15 minutes by synthesizing an entry in the shared RAM quota cache.
- Re-assert active strike blocks across refreshes so optimistic readings cannot
  resurrect a broken pair prematurely.
- Reset strikes and clear synthesized cache entry upon successful request.
- Keep exact-resetAt handling for genuine 0% exhausted readings.

Test Files

File What it tests
unit/embeddingsCore.test.js open-sse/handlers/embeddingsCore.js — core logic: body builder, URL router, headers, handler flow
unit/embeddings.cloud.test.js cloud/src/handlers/embeddings.js — cloud worker handler: auth, validation, rate limits, CORS

Coverage Summary (59 tests)

embeddingsCore.test.js (36 tests)

  • buildEmbeddingsBody: single string, array, encoding_format, default float
  • buildEmbeddingsUrl: openai, openrouter, openai-compatible-*, unsupported providers
  • buildEmbeddingsHeaders: per-provider header sets, fallback to accessToken
  • handleEmbeddingsCore input validation: missing, wrong type, null, empty
  • handleEmbeddingsCore success: response format, CORS, Content-Type, callbacks
  • handleEmbeddingsCore errors: 400/429/500, network error, invalid JSON
  • handleEmbeddingsCore token refresh: 401 retry, graceful fallback

embeddings.cloud.test.js (23 tests)

  • CORS OPTIONS: 200 response, empty body, correct headers
  • Authentication: missing key, bad format, old-format key, wrong key value, valid key
  • Body validation: invalid JSON, missing model, missing input, bad model
  • Happy path: single string, array, correct delegation, CORS header, machineId override
  • Rate limiting: all accounts rate-limited → 503 + Retry-After, no credentials → 400
  • Error propagation: non-fallback errors passed through, 429 exhausts accounts
  • machineId override: validates key, rejects wrong key
