docs: add self-evolution documentation and fix SOUL.md persistence

- Create 01-identity-evolution.md: Identity system architecture (SOUL.md, USER.md, change proposals, version management)
- Create 04-heartbeat-engine.md: Proactive behavior system (heartbeat config, alerts, proactivity levels)
- Create 06-context-compaction.md: Context compression system (token management, summarization, information retention)
- Update ZCLAW_AGENT_INTELLIGENCE_EVOLUTION.md: Add Phase 5 self-evolution UX roadmap
- Fix AgentOnboardingWizard: Persist SOUL.md and USER.md after agent creation
- Fix llm-service: Add Tauri kernel mode detection for memory system LLM calls
- Fix kernel: Kernel config takes priority over agent's persisted model
