85d75915ea Add character memory system for Tower P0 (#445)
- Record per-character memories of observations, actions, and social events
- Timmy actions (move, tend_fire, write_rule, carve, plant, speak, help, confront, examine, rest) now recorded
- NPCs (Marcus, Bezalel, Kimi, Ezra, etc.) record: moves seen, actions taken, speak/listen events
- Memory-informed NPC decisions: _has_recent() helper probes memory lookback
- Marcus: recent interaction increases social (speak) likelihood
- Bezalel: recent Timmy interaction reduces rest chance, increases forge activity
- Kimi: recent speaking decreases further speaking, increases study/plant
- Ezra: recent interaction increases help Timmy likelihood
- Claude: trust triggers and crisis memory reduce confront frequency
- Goal cycling: NPCs rotate through active_goal from goals list (15% chance/tick), changes logged
- Observation: all characters record who they saw in room at tick start

Closes #445
