M1: git pull in dev dir + rsync to install dir (install dir has no .git)
M2: use asyncio.create_subprocess_exec instead of subprocess.run
M3: add repo whitelist (only sanguo/sanguo_moziplus_v2 triggers auto-deploy)
S1: notify jiangwei-infra on rsync/pm2 restart failure
- Add auto-deploy logic in _handle_pr_closed after mail notification
- git pull origin main in install dir on merge
- Smart restart: only restart pm2 when src/templates/frontend/*.py changed
- Pure docs changes: pull only, no restart
- Deploy failure logged but does not block mail notification
- Update design doc §23 with auto-deploy section
