Add schema for agent personas, parts, traits, and character arcs

- Created tables for agent_personas, agent_parts, agent_traits, and character_arcs.
- Established relationships between personas, parts, skills, guardrails, and traits.
- Added arc stages and their corresponding parts, along with a persona_arc table to track current stages.
- Implemented cascading delete rules for referential integrity.
