Refresh the first request after the relevant invalidation without using a permanent positive-revision check.

The stale-request finding remains valid. A new list key starts with builtRevision === undefined, so its first request can omit refresh: true after the picker invalidates refs.

Do not fix this with state.revision > 0. The environment revision is kept alive and only increases. That condition would make the first request for every later-created or rebuilt key bypass the snapshot for the lifetime of the environment. It would not bypass every request from one key, but it could cause repeated unnecessary ref scans as query keys change. This conflicts with the stated first-load snapshot behavior.

Use a one-shot freshness marker scoped to the relevant invalidation and list key, and add a test for a key first built after invalidation. The available evidence does not establish a safe localized implementation for that marker, so no code diff is proposed.

Update the list-key freshness logic around builtRevision and
bypassServerSnapshot to use a one-shot marker scoped to the relevant
invalidation and key, so that key’s first request after invalidation refreshes
without making later-created keys permanently bypass snapshots. Add a test
covering a key first built after invalidation.
