feat(incidents): auto-incident detection + example-node Podman setup
Auto-incident detector:
- New app/tasks/incident_detector.py: post-glean error cluster detector
- Sliding window algorithm: source + N errors within window_s seconds
- Deduplication via issue_type='auto:{source_id}' + interval overlap check
- Respects TURNSTONE_AUTO_INCIDENT_THRESHOLD (default 5) and
TURNSTONE_AUTO_INCIDENT_WINDOW (default 600s) env vars
- 20 tests all passing
- Wired into glean_scheduler.run_once() and scheduler_loop()
- TURNSTONE_AUTO_INCIDENT env var to disable (default enabled)
Podman standalone improvements:
- REPO_DIR auto-detected from script location (no longer hardcoded to /opt/turnstone)
- DATA_DIR/PATTERNS_DIR/HF_CACHE_DIR configurable via env vars
- Bootstrap step copies host-specific sources-<hostname>.yaml on first run
- Auto-incident env vars passed through
example-node sources:
- patterns/sources-example-node.yaml: Sonarr, Radarr, Bazarr, Prowlarr,
Tautulli, autoscan, organizr, nextcloud, journal export
