feat: add dynamic watch paths for agent development

[samuveth]

Relates to: #930

Risks

Background

This setup is crucial for development because:

1. The agent depends on the packages listed in WORKING_FOLDERS
2. When you make changes to any of these packages, they get compiled to their respective dist directories
3. The agent needs to restart with the new changes for them to take effect
4. This automation saves developers from having to manually restart the agent every time they make changes to dependent packages
