iliya 6aec33ae33 feat: enhance notification and task management features
- Updated notification configuration to separate settings for lead and user inbox messages, improving user control over notifications.
- Enhanced the handling of inbox message notifications to respect individual inbox settings.
- Introduced new IPC methods for managing watched directories, allowing for more granular file monitoring.
- Improved task management by implementing work intervals for task status transitions, ensuring accurate tracking of task progress.
- Added validation for task creation and configuration, ensuring proper input handling for project paths and task properties.
