- Enhanced daily logs with focus, work-items, and blockers properties.
- Updated work-item notes to include systems, workstreams, people, and related properties.
- Improved context maintenance guidelines to ensure accurate and durable project knowledge.
- Refined base filters to exclude template files and ensure only relevant notes are displayed.
