# Plug Stale Task Hole Implementation

## Summary
Added stale-task detection, `--touch` command in status.py, and updated guard plugins to block edits on stale tasks.

## Changes

### scripts/status.py
- Added `--touch` command that resets the activity clock on a task
- Stale detection: tasks in edit-allowed phases >30 minutes are considered stale
- `--can-edit` returns `stale_task` reason when a task is stale
- Added `stale_task` and `stale_minutes` to JSON output

### plugins/automaton-guard/plugin.ts
- Added stale task detection: if `--can-edit` returns `stale_task` reason, the guard blocks with a message suggesting `--touch` or new task creation
- Parses `staleTask` and `staleMinutes` from JSON response

### automaton/dashboard/core/task.py
- Added stale task awareness in the dashboard

### tests/test_task.py
- Added tests for stale task detection and touch functionality
