- Replaced inline drawing logic for task comments with a new `drawCommentBubble` function to enhance readability and maintainability.
- The new function encapsulates the drawing of a speech-bubble icon, including the rounded rectangle body, tail, and inner dots to suggest text.
Particle direction:
- Added `reverse` flag to GraphParticle — when true, particle flies
from target → source (reverse of edge direction)
- Messages FROM teammate TO lead now fly member→lead (was lead→member)
- draw-particles.ts swaps from/to nodes when reverse=true
Reverted system message filter:
- Removed #isSystemMessage — all messages shown as particles again
(user wants to see idle_notification etc.)
- Added visual differentiation for 'task_comment' particles, adjusting size and glow effects.
- Updated drawing functions to handle new particle kind, ensuring proper rendering in the graph.
- Introduced a merge function for particles to prevent duplicates during state updates.
- Enhanced color constants for better visual representation of different particle types.
