Introduces dedicated TypeScript interfaces for all drag-and-drop event payloads, enhancing type safety and developer experience.
Centralizes drag event detection and emission within `DragDropManager`. Refactors `AllDayManager`, `HeaderManager`, and `EventRendererManager` to subscribe to these typed events, improving decoupling and clarifying responsibilities.
Resolves known inconsistencies in drag event payloads, especially for all-day event conversions. Adds a comprehensive analysis document (`docs/EventSystem-Analysis.md`) detailing the event system and planned improvements.
Prepares the calendar component for month view implementation
by introducing a strategy pattern for view management,
splitting configuration settings, and consolidating events
into a core set. It also removes dead code and enforces type safety,
improving overall code quality and maintainability.
Addresses critical issues identified in the code review,
laying the groundwork for efficient feature addition.
