[Mnemosyne] Memory Birth Animation System

New memories shouldn't just appear — they should arrive. This PR gives crystals a materialization entrance that makes the holographic archive feel alive.

Changes

nexus/components/memory-birth.js — New birth animation engine
- Elastic scale-in: Crystals grow from 0 → full size with elastic easing over 1.8s
- Bloom flash: Emissive intensity spikes at 30% through the birth, then fades
- Neighbor pulse: Existing memories within 8 units brighten momentarily when a new memory is born nearby (distance-falloff)
- Connection line grow: Connection lines fade in progressively over 1.2s
- wrapSpatialMemory(): Auto-intercepts placeMemory() so every new crystal gets a birth animation — zero config needed
app.js — Integration
- Import MemoryBirth module
- Initialize alongside SpatialMemory
- Wrap placeMemory() for automatic triggering
- Call MemoryBirth.update(delta) in the render loop

Visual Effect

t=0.0s  Crystal at scale 0, invisible
t=0.3s  Bloom flash peak — emissive 4x normal
t=0.8s  Elastic bounce overshoot (scale ~1.15)
t=1.2s  Neighboring crystals pulse in recognition
t=1.8s  Fully materialized, normal rotation begins

Design Decisions

Elastic ease, not linear: Gives the birth a "pop" feeling — crystals snap into existence with personality
Neighbor radius 8 units: Enough to reach most crystals in the same region without bleeding across the archive
Auto-wrapping: No changes needed to existing code that calls placeMemory() — the intercept is transparent
Performance: O(n) per birth for neighbor check, but births are rare events (not per-frame)
