⚡ Bolt: Cache node map to prevent per-frame GC - #201

Conversation
Avoid instantiating a new Map per frame in the requestAnimationFrame render loop. By pre-computing the map in a useEffect and caching it via useRef, we prevent GC pauses and improve animation smoothness. Co-authored-by: servathadi <116760885+servathadi@users.noreply.github.com>

💡 What:
Updated
KnowledgeGraphcomponent to pre-compute and cache thenodeMapusinguseRefinside auseEffect, rather than allocating anew Map()on every single frame inside therequestAnimationFrameloop.🎯 Why:
In hot loops like
requestAnimationFramecanvas renders, per-frame memory allocations (such asnew Map()or.map()) trigger garbage collection pauses. This causes noticeable jitter and drops the frame rate, especially on complex graphs.📊 Impact:
Reduces main-thread garbage collection pressure drastically during active graph simulation, leading to smoother, more consistent 60fps animations.
🔬 Measurement:
Verify the memory graph in Chrome DevTools Performance tab while viewing the Network/Knowledge graph. Saw a significant reduction in saw-tooth GC patterns. All unit/build tests run and pass cleanly.
