Pull Request Overview

This PR introduces the foundational infrastructure for a new standalone binary called vmcp (Virtual MCP Server), which will serve as an aggregation proxy for multiple MCP (Model Context Protocol) servers. The implementation focuses on establishing the binary structure, CLI commands, and build/CI configuration without the full functional implementation.

Key Changes:

• Added new vmcp binary with CLI structure (serve, validate, version commands)
• Integrated build tasks and container image builds for the new binary
• Extended CI/CD pipeline to build and publish vmcp container images
