Expose snapshotsForCwds for managed Codex.

When config.setupMode === "managed", CodexDriver.create returns before it attaches the batch callback. CodexManagedProvider exposes only snapshotForCwd, although it already resolves the runtime configuration and environment for workspace skill probing.

ProviderRegistry skips instances without snapshotsForCwds during refreshes. Managed Codex workspace snapshots can therefore remain stale after skills are installed.

Add snapshotsForCwds to the managed instance. Use the resolved runtime configuration and environment with probeCodexSkillsForCwds, as the standard Codex path does.

Review comment at @apps/server/src/provider/Drivers/CodexDriver.ts at line 396:
Add snapshotsForCwds to the managed instance returned by CodexDriver.create,
using the resolved runtime configuration and environment with
probeCodexSkillsForCwds, as in the standard Codex path, so ProviderRegistry can
refresh managed workspace snapshots.
