Clear available_* only when the deployed ref equals it, drop the unused
poll source, stop leaking internal errors to CI, use the request-scoped
logger, validate X-Request-ID, re-read jobs once after the timeout,
report refused when no target ref exists, and tidy UI, deploy and docs.
ApplySnapshot and UpsertService now take a FOR SHARE lock on the agent's
row and refuse with model.ErrRevoked when it is revoked. RevokeAgent's
UPDATE waits on that lock, so an in-flight snapshot or upsert can no
longer bring a revoked agent's services back after the revoke cleanup.
- inventory: resolve the image reference via ContainerInspect when a moved
tag makes ContainerList report the image ID
- store: allow reusing a revoked agent's name (partial unique index) and
mark the revoked agent's compose/container services removed
- web: publish a services event on revoke; no-store on the one-time token page
- webauth: reject empty OIDC state; accept the CSRF form token from the body only
- agent conn: bound the WebSocket handshake to 30s
- hub: log agent_replaced when a connection replaces an older one
