- use sqlx migrate!() instead of broken split(';') — triggers now work
- seq via AUTOINCREMENT — no race conditions, monotonic ordering
- replace ?since= with ?after_seq= — cursor-based, no timestamp format issues
- replace all unwrap() with typed errors (404, 409, 400, 500)
- reply_to same-channel enforced in route handler
- add biome for frontend linting
