Begin migrating the thread write codepaths to ThreadStore. This starts using ThreadStore inside of core session code, not only in the app server code. Rework the interfaces around thread recording/persistence. We're left with the following: * `ThreadManager`: owns the process-level registry of loaded threads and handles cross-thread orchestration: start, resume, fork, lookup, remove, and route ops to running CodexThreads. * `CodexThread`: represents one loaded/running thread from the outside. It is the handle app-server and callers use to submit ops, inspect session metadata, and shut the thread down. * `LiveThread`: session-owned persistence lifecycle handle for one active thread. Core session code uses it to append rollout items, materialize lazy persistence, flush, shutdown, discard init-failed writers, and load that thread’s persisted history. * `ThreadStore`: storage backend abstraction. It answers “how are threads persisted, read, listed, updated, archived?” Local and remote implementations live behind this trait. * `LocalThreadStore`: local ThreadStore implementation. It owns the file/sqlite-specific details and keeps RolloutRecorder as a local implementation detail. This is a few too many Thread abstractions for my liking, but they do all represent different concepts / needs / layers. Migration note: in places where the core code explicitly requires a path, rather than a thread ID, throw an error if we're running with a remote store. Cover the new local live-writer lifecycle with focused tests and preserve app-server thread-start behavior, including ephemeral pathless sessions.
