refactor(trace): separate daemon, hook, and session ownership

[rgao-coreweave]

Summary

Separate daemon transport, hook handling, and per-session tracing into explicit owners:

• Daemon: Unix socket, Weave setup, and process lifecycle
• HookHandler: hook validation, per-session ordering, dispatch, and session lookup
• Session: transcript state and root-turn lifecycle

Root turns are created from live conversation hooks. SessionEnd can reconcile the final transcript turn after restart, while daemon shutdown only finalizes turns already known to the process.

Validation

• npm run check
• 74 tests pass
