claude-code - 💡(How to fix) Fix [Bug] /compact command does not trigger statusline refresh

Bug Description /compact does not trigger a statusline refresh. After /compact completes, the statusline continues to display the previous render (including the pre-compact token count) until something else forces a re-invocation, e.g. submitting a prompt or resuming the session. As a result, the displayed context size appears stale even though it's just a frozen frame from before the compact.

Repro: configure a custom statusline that shows context tokens, run /compact, observe the old token count remain on screen until the next prompt or a session resume.

Expected: the harness re-invokes the statusline command on /compact completion (alongside the existing SessionStart:compact hook) so the rendered output reflects post-compact state.

Custom statuslines that try to detect post-compact freshness by inspecting the transcript work correctly when invoked, but the harness doesn't invoke them at this moment, so there is no script-side workaround.
