v0.7.5

Fixed

• The stats/analytics endpoint no longer crashes on PostgreSQL. The message time-series query grouped by an output alias named timestamp — a reserved type keyword in PostgreSQL — so GROUP BY timestamp was not read as the alias and the query failed with "column m.createdAt must appear in the GROUP BY clause" (SQLite tolerated it, so unit tests on the SQLite test DB never caught it). The alias is now bucket; the API response field is unchanged. (#474)

Documentation

• Added a Traefik / Coolify reverse-proxy guide to the troubleshooting FAQ: WebSocket forwarding, the docker-proxy double-hop that causes intermittent 504s behind Coolify (held-open Socket.IO connections exhausting the pool to the single-port upstream), and idle-timeout tuning. (#467)
