Remove context tool and update tool_index with resource tool

- Remove context tool from all Tool enum matches
- Remove context.rs file and module references
- Update tool_index.json to replace context with resource tool
- Fix remaining context references in hooks.rs and tool_manager.rs
- LLM now has unified resource tool instead of separate context tool
- Clean separation: /resource slash command + resource LLM tool
