Session lifecycle logging gains a new detached outcome

What

The list of possible session lifecycle outcomes that Claude Code records now includes detached, in addition to the existing recreated, ended, cleared, and start_failed.

Why

This lets Claude Code distinguish a session becoming detached from the other existing outcomes, giving more precise session lifecycle information.
