Introduce a ThreadStore interface for mediating access to the filesystem (rollout jsonl files + sqlite db) based thread storage. In later PRs we'll move the existing fs code behind a "local" implementation of this ThreadStore interface. This PR should be a no-op behaviorally, it only introduces the interface.
