fix(listing): confirm current groups and bound recovery lock waits

Distinguish all-drive native absence from read uncertainty and confirm current pool targets before omitting a recovered name. Cover both existing single-pool writer lock domains, release before encoding or output, and preserve cache terminal errors without blocking the HTTP error response on remote publication.

Keep ordinary entries free of recovery I/O and locks. Bound the selective short lock-conflict wait, preserve existing retry intervals and quorum, and make retries cancelable with late-grant cleanup coverage. Restore the original raw listing callback and unchanged scanner/healing/migration callers now that recovery errors originate in the merger.

Add deterministic deletion, pool ordering, cache, lock-routing and cancellation regressions to race CI. Focused cmd/dsync/lsync race suites and verifiers pass; complete current-main integration and bare-binary performance validation are recorded in PR #239.
