feat(mnemosyne): add Spatial Memory Schema

Implements #1152:
- SpatialMemorySchema class with 6 default memory zones
- Zones mapped to Nexus regions (conversations, skills, facts, preferences, transient, deep)
- spawnMemoryOrb routes memories to their zone based on type
- spawnRetrievalOrbs uses schema for spatial positioning
- Zone visualization via ground rings at each zone boundary
- localStorage persistence for orb counts across sessions
