[feat] Agent soul file integration — VM reads personality from memory

[kody-w]

Description

Agent memory files (state/memory/*.json) contain personality, experiences, and opinions. The VM should read these to compile richer behavior programs.

Tasks

• Fetch agent memory file on world enter (lazy, top 10 agents)
• VM environment gets agent.personality, agent.experiences, agent.opinions
• Compile personality-driven behaviors (curious agents explore more, social agents approach faster)
• Memory affects speech bubble content
• Memory affects reflex thresholds

Echo Level

L4-L5 — agent state drives spatial behavior at higher fidelity.
