feat: Add client-side auto-update hook for openclaw

- scripts/autoupdate-openclaw.sh: Checks for and pulls updates from fork
- Runs in background on session start (via ~/.claude/settings.json hook)
- Rate-limited to once per hour
- Logs to ~/.claude-code-pp/logs/autoupdate.log
- Only fast-forwards, skips if local changes present
