Eric Traut 2f0a5d5516 Avoid scanning archived rollouts when archiving threads (#41908) ...

## Why

Archiving a thread only needs to locate rollout files that have not already
been moved, so reading the entire rollout archive on every request is
unnecessary.

## What changed

- Add `RolloutReferenceIndex::scan_unarchived` to scan only the active
  `sessions` directory.
- Use the active-only index when archiving threads while retaining full scans
  for operations that require archived-history reference counts.
- Cover discovery of compressed and uncompressed active rollouts and exclusion
  of archived and unrelated rollouts.
