Replace the Phase 2 in-flight chat gate (buffered channel) with a real SQLite-backed job queue and single worker loop. Every /api/chat request now creates a job row, blocks until the worker completes it, and returns the result transparently. Key changes: - internal/store: NextJob (drain-by-model ordering), IncrementAttempt, ResetInterruptedJobs, DeleteTerminalJobsBefore; busy_timeout pragma - internal/worker: single-threaded worker loop with Notifier for sync handler completion signaling; retry on ConnectionError, terminal fail on HTTPError; crash recovery resets interrupted jobs on startup - internal/webhook: dispatcher infrastructure for async webhook delivery - internal/server: chat handler rewritten to enqueue+wait; old chatGate removed; embeddings remain direct concurrent proxies (ADR-0013) - internal/config: FOREMAN_MAX_ATTEMPTS, FOREMAN_JOB_TTL Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
