/**
* Working/idle detection for an interactive Claude pane.
*
* The bug this pins: Claude redraws the composer (`❯`) about once a second all
* the way through a turn, so the old "saw a ❯, wait 2s, call it idle" rule
* flipped a busy session to idle two seconds into every turn. Measured on a live
* worker: `GET /api/sessions` reported `idle` for a session that had been
* running for 17 minutes and was mid-tool-call.
*
* The status-line fixtures below are verbatim captures from live panes
* (`tmux -L codeman capture-pane -p`) on Claude Code 2.1.220.
