…loraOrg#924) Add a per-endpoint circuit breaker to the /api/gateway downstream proxy path so that repeated upstream failures trip an isolated breaker per apiId, causing subsequent requests to fast-fail with HTTP 503 instead of waiting for a timeout. Changes: - src/routes/gatewayRoutes.ts: wrap upstream fetch in breakerRegistry.getOrCreate(apiId).execute() with a pre-flight wouldBlock() check before billing so callers are never charged when the circuit is OPEN - src/lib/circuitBreaker.ts: add wouldBlock() method that replicates execute() cooldown logic; set lastFailureTime in trip() so pre-check correctly computes the cooldown window - src/config/env.ts: add GATEWAY_BREAKER_FAILURE_THRESHOLD, GATEWAY_BREAKER_COOLDOWN_MS, GATEWAY_BREAKER_SUCCESS_THRESHOLD - .env.example: document the three new env vars - src/routes/gatewayRoutes.circuitBreaker.test.ts: 7 focused tests covering CLOSED pass-through, OPEN fast-fail, billing skip, per-API isolation, threshold-based tripping, and HALF_OPEN recovery Closes CalloraOrg#924
