New telemetry categories record why and how a session was started or woken up

What

Claude Code now records, in telemetry, a category explaining what triggered a session to start. The options include:

  • user
  • scheduled-task
  • sleep-auto-resume
  • quit-auto-resume
  • remote-restart-auto-resume
  • ci-monitor
  • dispatch
  • side-session-brief
  • side-session-start
  • side-session-wake
  • other

A separate wakeup_source field records whether a wakeup came from loop_wakeup or schedule_wakeup.

Why

This gives more detailed visibility into how sessions get started or resumed, whether by a person, a scheduled task, auto-resume after sleep or a quit, or other automated triggers.
