Harden startup rollout migration against concurrent updates ( #40499 ) ...
## Why
Another Codex process can write, archive, or compress a rollout while startup
migration is inspecting it. This can leave a discovered path stale or make an
in-progress rollout look empty or busy.
## What changed
- Wait for rollout maintenance to finish before starting background migration.
- Re-read empty rollouts under their writer lock and retry busy rollouts on a
later startup.
- Find archived or compressed rollouts again when their paths change after
discovery, while keeping terminal failures from blocking the startup cursor.
## Testing
Added coverage for maintenance contention, writer-owned empty rollouts, busy
rollout retries after archive and compression moves, permanent failure skips,
pending recovery, and paths that move after discovery.
