Update Design Document and Refactor Execution Phases

- Revised the design document to improve clarity in the deduplication timing table format.
- Updated the `Resources` struct to include a new `Inspiration` phase and adjusted the descriptions for existing phases.
- Enhanced the `ExecutionPhase` constants to reflect the new phase structure, adding a `PhaseLearning`.
- Improved the documentation for the private knowledge base categories and the Activity Monitor API features for better readability.
- Introduced new types for alert rules and actions in the monitoring configuration, expanding the alerting capabilities.
