sqlc reads all migrations into every package's schema, so the
addition of acp_* tables and workspaces.active_main_session_id
in migration 0006 propagates type definitions and SELECT
column lists across all sub-packages. No code logic changes.
T1 added jobs table and workspace_worktrees.prune_warning_at column but
sqlc generate was not re-run for all modules. This catches the audit,
notify, project, and user models up; chat partially regenerated already.
Workspace's regen is part of T3 (next commit).
