Pull Request Overview
This PR adds an experimental MCP (Model Context Protocol) server mode to DepGate, exposing dependency analysis tools via the official MCP Python SDK. The implementation adds a new mcp subcommand that exposes three tools: Lookup_Latest_Version, Scan_Project, and Scan_Dependency.
- Adds MCP server implementation with stdio transport support
- Implements JSON schema validation for MCP tool inputs/outputs using Draft-07 schemas
- Extends test mocks to handle Session.request() calls and additional metadata fields
- Updates documentation and package metadata for v0.6.0 release
