Add resource tool for LLM to provide unified view

- Create new resource tool that handles both pinned and indexed resources
- Add resource tool to Tool enum and all match statements
- Register resource tool in tool_manager.rs
- LLM can now use 'resource' tool instead of just 'context'
- Provides unified interface for both storage types
