- Add interruptible stop events to background workers so shutdown
wakes out of long sleeps instead of waiting on fixed delays.
- Stop scan managers, repair worker, executors, and cleanup helpers
deterministically so process exit does not leave background threads
alive.
- Add startup warnings for stale SQLite WAL/SHM sidecars so unclean
shutdowns are easier to spot before init/migration errors cascade.
- Prevent forced kills from leaving SQLite sidecars behind, which
made rollbacks to older branches fail with malformed database
errors.
Use UUID nonces to correlate requests/responses and robustly handle interleaved stats/heartbeat messages from the Hydrabase server. Adds _extract_stats and _extract_results helpers, records last_peer_count and timestamp, and loops on recv() with timeouts to drain non-result messages until the matching response (or a results message without a nonce) arrives. Mirrors the same nonce/send-and-drain logic in HydrabaseWorker, adds necessary imports (time, uuid), and improves logging and timeout handling to avoid returning stale or misattributed data.
Introduce a Hydrabase P2P mirror worker and integrate it into the web UI and server flows. Adds core/hydrabase_worker.py: a background thread with a capped queue (1000), enqueue API, rate limiting, basic stats (sent/dropped/errors), and logic to send JSON requests over a provided WebSocket (responses received and discarded). Integrates the worker into web_server.py (import, startup init, status/pause/resume endpoints, and enqueues queries from multiple search endpoints when dev mode is enabled). Adds UI elements, JavaScript polling/toggle logic, and CSS styling for a Hydrabase status button in webui (index.html, static/script.js, static/style.css) to display and control worker state.
