Sync system was timing out because discovery endpoints (keyword, changes)
also ran schema extraction (~10-15s per tool). Now discovery is fast
(npm metadata + DB writes only) and a new /api/sync/enrich endpoint
handles schema extraction in time-budgeted chunks.
Railway executor was crashing without restarting due to unhandled promise
rejections, no restart policy, and no health checks. Added crash
protection, graceful shutdown, cache size limits, railway.toml with
ALWAYS restart policy, and upgraded Deno from 1.39 to 2.1.9.
