- Workers now git clone --depth=1 per issue instead of sharing base repos
with worktrees. Eliminates all contention and branch collision errors.
- Watchdog file_issue uses temp file + sys.argv for safe JSON escaping
- Watchdog zombie detection only kills processes >5min old (was killing
legitimate git pushes from active workers)
- Simplified cleanup to plain rm -rf (no worktree bookkeeping needed)

Workers now pick ANY open issue (assigned to them OR unassigned) and
self-assign via Gitea API before starting work. No more empty queues.
