fix: Improve MCP server robustness and debugging

- Refactor  for more reliable project root detection, particularly when running within integrated environments like Cursor IDE. Includes deriving root from script path and avoiding fallback to '/'.
- Enhance error handling in :
    - Add detailed debug information (paths searched, CWD, etc.) to the error message when  is not found in the provided project root.
    - Improve clarity of error messages and potential solutions.
- Add verbose logging in  to trace session object content and the finally resolved project root path, aiding in debugging path-related issues.
- Add default values for  and  to the example  environment configuration.

 - **Refactor project root handling for MCP Server:**
   - **Prioritize Session Roots**: MCP tools now extract the project root path directly from `session.roots[0].uri` provided by the client (e.g., Cursor).
-  - **New Utility `getProjectRootFromSession`**: Added to `mcp-server/src/tools/utils.js` to encapsulate session root extraction and decoding.

 - Update MCP tool naming to follow more intuitive conventions that better align with natural language requests in client chat applications.
