v1.18.4 Enhanced memory graph tooltip interaction and layout optimization

Enhanced

• Memory Graph Tooltip Interaction: Significantly improved tooltip usability
  • Added hover state tracking to prevent accidental tooltip triggers
  • Tooltip only appears when mouse is truly over a node
• Mouse can smoothly move from node to tooltip for scrolling long content
  • Intelligent positioning to prevent tooltip from going off-screen
  • Added custom scrollbar styling for better visual experience
  • Fixed tooltip disappearing immediately when trying to scroll

Improved

• Memory Graph Layout Optimization: Better handling of large node counts
  • Dynamic link distance based on node importance (80-180px range)
  • Stronger repulsion force for important nodes (-300 to -500)
• Adaptive label spacing based on node importance
  • Zone attraction strength decreases as node count increases
  • Larger radial distance for zones with many nodes
  • Significantly reduced node overlap in dense graphs

Fixed

• Critical: Fixed JavaScript syntax error in generated HTML
  • Removed duplicate }, 500); in setTimeout closure
  • HTML files now load correctly in all browsers
• Tooltip Interaction: Fixed tooltip disappearing when mouse moves to it
  • Added isMouseOverTooltip flag to track tooltip hover state
  • Tooltip stays visible when mouse transitions from node to tooltip
  • Only hides after mouse leaves both node and tooltip areas

Technical Details

• Added currentHoverNode variable to track active node hover
• Added isMouseOverTooltip flag for tooltip interaction state
• Enhanced collision detection with importance-based spacing
• Dynamic force parameters based on zone node density
• Improved tooltip positioning algorithm with boundary detection
