* feat(io): Migrate pkg/mcp to use Medium abstraction
- Replaced custom path validation in `pkg/mcp` with `local.Medium` sandboxing.
- Updated `mcp.Service` to use `io.Medium` for all file operations.
- Enhanced `local.Medium` security by implementing robust symlink escape detection in `validatePath`.
- Simplified `fileExists` handler to use `IsFile` and `IsDir` methods.
- Removed redundant Issue 103 comments.
- Updated tests to verify symlink blocking.
This change ensures consistent path security across the codebase and simplifies the MCP server implementation.

- Enhanced `local.Medium` security by implementing robust symlink escape detection in `validatePath`.
- Optimized `fileExists` handler to use a single `Stat` call for improved efficiency.
- Cleaned up outdated comments and removed legacy validation logic.
- Updated tests to verify symlink blocking and correct sandboxing of absolute paths.
