Unity Timeline Interaction System Integration (#17)
- Added InteractionTimelineAction component for timeline-driven interactions - Implemented custom editor for timeline event mapping - Updated interaction event flow to support timeline actions - Enhanced character move target configuration - Improved inspector UI for interactable components - Added technical documentation for interaction system - Refactored interaction action base classes for extensibility - Fixed issues with character binding in timelines Co-authored-by: Michal Pikulski <michal@foolhardyhorizons.com> Co-authored-by: Michal Pikulski <michal.a.pikulski@gmail.com> Reviewed-on: #17
