Unify auth middleware and remove X-User-ID trust, add project_members
authorization, sandbox workspaces via resolver, and admin-only reconcile
by run_id. Introduce goose migrations with startup schema gate, fail closed
when DB unavailable outside explicit ALLOW_IN_MEMORY, bundle web/dist in
app Dockerfile, and remove frontend pseudo-login fallback.
Extend taskrun executors to return full TaskRunResult, finalize assistant
placeholder content with artifact metadata, and map quality_failed terminal
state instead of metadata-only updates.
