- Browser WS clients can now send {"type": "subscribe", "message_types": [...]}
to only receive specific message types. Default is all (no change for browsers).
- Discord bot subscribes to only "rare" and "chat" — eliminates 82GB+ of
unnecessary telemetry/vitals/inventory traffic.
- Idle detection now has a 5-minute grace period before firing Discord alerts,
preventing false positives on brief idle states.
- Added DISCORD_ACLOG_WEBHOOK env var to docker-compose.yml for death/idle alerts.
