Add sudo translator agent with whitelist and user lock

- New sudo chat trigger: 'sudo <request>'
- Authorized user only (configurable, default slingshooter08)
- Uses command_model to translate natural language to JSON commands
- Executes commands through existing whitelist/validator pipeline
- No God persona or speech call in sudo mode
- Added sudo_enabled/sudo_user/sudo_max_commands config keys
- Added common give-item alias normalization (wood->oak_log, bed->white_bed)
- Updated README with sudo usage and config docs
