Rewrite island:analyze with letta-code-sdk agent
Replace rule-based keyword matching with LLM-powered analysis:
- Agent receives full island context (vertices, edges, domains, contributors)
- Agent calls island_save tool with structured analysis
- Produces real narrative synthesis instead of template strings
- Removes carry dependency — works from discovered component data alone
- Keeps same SQLite schema, CLI flags, and output format
