Create migration m20260417_000001_add_stream_to_room_ai that adds
the `stream BOOLEAN NOT NULL DEFAULT true` column to room_ai.
The model definition includes this field but the original migration
was missing it.
Also format libs/api/room/ws.rs and add gitdata.ai to allowed
WS origins.
m20260411_000003_add_workspace_id_to_project was running before
m20250628_000013_create_project, causing "relation project does not exist".
Move all project table CREATEs before workspace migrations.
