Refactor Assistant script loading and management

- Updated the script loading process to load both hook scripts and other scripts from the src directory, improving organization and clarity.
- Introduced a new `Scripts` field in the Assistant struct to store additional scripts, enhancing the flexibility of script management.
- Removed deprecated script loading functions and streamlined the loading logic to ensure better maintainability and performance.
- Adjusted the handling of timestamps for script updates, ensuring accurate tracking of script modifications.
