bbrown-oai c6327eba6a Filter rollout filenames before checking compressed siblings (#53997)
## Why

Filesystem lookups by thread or rollout ID check whether unrelated compressed rollouts have an uncompressed sibling. These checks are unnecessary when the filename does not match the requested ID.

## What changed

Apply the thread or rollout ID filter before resolving plain/compressed file precedence. Preserve preference for uncompressed files and selection of the newest rollout for a thread.

## Testing

Extend lookup tests to cover unrelated compressed files, uncompressed-file precedence, missing rollout IDs, and rollout ID tie-breaking for files with the same timestamp.
