* 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.
