Charlie Marsh dddc3c0a79 Skip unrelated indexed rollouts during selected thread migration (#57483 )

## Why

Migrating selected threads reads rollout headers even for unrelated threads. Use the state database to skip files whose indexed owner and canonical filename agree that they belong to an unselected thread.

## What changed

- Read thread IDs and rollout paths without creating or migrating the state database, and fall back to header inspection if the index cannot be read immediately.
- Keep inspecting selected, unindexed, misnamed, and conflicting paths so rollout headers still determine ownership.
- Recognize stable thread IDs in reverted rollout filenames and match plain and compressed paths when filtering.

## Testing

Add a regression test covering pruning of unrelated indexed rollouts, including archived and compressed files, while retaining header inspection for selected and ambiguously named files.

Thread Store

codex-thread-store is the storage boundary for Codex threads. It defines the ThreadStore trait plus local and in-memory implementations. Other storage implementations may live outside this repository.

Responsibilities

ThreadStore::append_items is the raw canonical history append API. It does not infer metadata from item contents.
ThreadStore::update_thread_metadata is the only thread metadata write API. It accepts a single literal metadata patch shape, regardless of whether the caller is applying a user/API mutation or facts derived above the store from appended history.
LiveThread is the preferred API for active session persistence. It owns a per-thread metadata sync helper, applies the rollout persistence policy, appends canonical history, and then sends metadata patches through ThreadStore::update_thread_metadata.
ThreadManager routes metadata mutations for loaded and cold threads through one entrypoint. Loaded threads use their LiveThread; cold threads go directly to the store.
LocalThreadStore persists history through codex-rollout JSONL files and persists queryable metadata through the SQLite state database when available. Local explicit metadata mutations also maintain JSONL/name-index compatibility so reading old or SQLite-less local storage keeps working.
RolloutRecorder is the local JSONL writer. It writes already-canonical items for ThreadStore::append_items; it no longer decides metadata updates for live thread-store appends.
core/session creates or resumes LiveThread handles and does not need to know whether persistence is backed by local files or another store.

Direction

New metadata observation semantics should live above ThreadStore. Stores persist explicit metadata fields, but raw history appends remain history-only.
