2026-01-07Add ThrottleManager for cross-domain rate limitingDanConwayDev
Implements ThrottleManager which manages all per-domain DomainThrottle instances and provides: - Throttle status checking via is_throttled() for sync URL selection - Request tracking via start_request()/complete_request() - Identifier queue management via enqueue_identifier() - Automatic domain throttle creation on first access - Thread-safe access via DashMap with Mutex-wrapped throttles The manager uses the configured max_concurrent and max_per_minute limits for all domains. Trigger-based queue processing (set_context, process_queued_identifier) will be added after SyncContext is available. Tests verify: - is_throttled reflects domain capacity correctly - enqueue_identifier creates domain throttle if needed - start_request creates domain throttle if needed
2026-01-07Add DomainThrottle for per-domain rate limitingDanConwayDev
Implement per-domain throttling for purgatory sync operations: - Concurrent request limit (max in-flight requests per domain) - Rate limit (max requests per minute via sliding window) - Fair round-robin queue processing across identifiers - In-progress tracking to prevent duplicate fetches - Tried URL tracking per identifier Add indexmap dependency for ordered iteration in round-robin queue. Includes 6 unit tests covering: - Concurrent limit enforcement - Rate limit enforcement (sliding window) - Round-robin fair processing - In-progress identifier skipping - Round-robin index adjustment on removal - Tried URL merging on re-enqueue
