What this does

Adds force-directed gravity well clustering to Project Mnemosyne. When the app loads, SpatialMemory.runGravityLayout() runs 20 iterations of a force-directed layout on all placed memory crystals, then stops (positions are baked, not updated per-frame).

Force rules (per iteration)

Attraction: each crystal moves 10% closer to the centroid of same-category crystals in its region
Repulsion: each crystal is pushed 5% of the distance away from the nearest unrelated crystal
Displacements are accumulated before applying each iteration (avoids order-of-iteration bias)

Persistence

After the layout run completes, saveToStorage() is called to bake the final positions into localStorage. On next load the crystals start from those baked positions.

Files changed

nexus/components/spatial-memory.js — added runGravityLayout() function and exported it
app.js — call SpatialMemory.runGravityLayout() after demo memories are placed

Add force-directed layout that runs on load (20 iterations, then stops):
- Same-category crystals attract 10% closer to their group centroid per iteration
- Each crystal repels 5% away from its nearest unrelated crystal
- Displacements are accumulated per-iteration before applying (no order bias)
- Final positions baked to localStorage after layout completes

Expose `runGravityLayout()` from SpatialMemory module and call it in
app.js after all demo memories are placed, so every session starts with
naturally clustered crystals.

Fixes #1175
