The stop_sequences contained "```" which caused the model to stop

Implements the AI-powered indexing component of RFC 0010:
- Add indexer module with LlmProvider abstraction
- Integrate qwen2.5:3b via Ollama for local file analysis
- Extract summaries, relationships, and symbols from source files
- Support partial indexing for files >1000 lines
- Wire indexer to all CLI index commands (--all, --diff, --file, --refresh)
The indexer generates structured YAML output with:
- One-sentence file summaries
- Relationship descriptions for semantic search
- Symbol-level indexing with line numbers
