feat: add MCP server example for sandboxed JavaScript execution

Add an MCP (Model Context Protocol) server that exposes an
execute_javascript tool, allowing AI agents to run arbitrary JavaScript
inside an isolated Hyperlight micro-VM sandbox with strict CPU time
limits and automatic snapshot/restore recovery after timeouts.

Includes server implementation, demo scripts (PowerShell and Bash),
vitest test suite, and documentation.
