[BUG] Status line shows stale shells/monitors counters after /clear with nothing running

Summary

The Claude Code built-in status line continues to display non-zero "shells" and "monitors" counters even when there are no background tasks, cron jobs, or monitor processes actually running. The counters appear to be sticky / not reset by /clear.

Repro

1. Run a session that at some point spawns background bash tasks and/or Monitor watches.
2. Let those tasks complete (or stop them).
3. Run /clear.
4. Observe the status line still shows e.g. 2 shells, 2 monitors.

Expected

After /clear, the counters should reflect the current state — 0 shells, 0 monitors when nothing is active.

Actual

Counter stays at the previous value indefinitely.

Evidence from this session

After /clear, the status line showed 2 shells, 2 monitors, but:

• CronList → cleared (only one one-shot cron existed; deleted)
• TaskList → "No tasks found"
• ps -ef | grep -E 'tail -f|inotify|monitor|while true' → no matches

So no background work was actually live — the counter was stale.

Environment

• Claude Code: Opus 4.7 in CLI
• Platform: Linux 6.17.0-29-generic
• Shell: bash

Impact

Cosmetic, but misleading — users (and Claude) cannot tell from the status line whether background work is genuinely active or the indicator is stuck.
