feat: Implement commercial-style updater with script removal/replacement

- Add REMOVE_SCRIPT command to delete old scripts before update
- Add RENAME_SCRIPT command for future script name management
- Use 3-step process: remove old → install new → rename
- Update_Receiver now handles script inventory management
- Follows commercial SL updater patterns with remove-then-replace
