Fix user switch: Use proper login shell with .bashrc sourcing

- Create ~/.clawdbot-init that displays welcome message once
- Add sourcing to .bashrc (removes itself after first run)
- Use simple 'exec sudo -i -u clawdbot' without complex redirects
- This ensures proper login shell initialization and user switch
