First example of the binary server type — a compiled Rust MCP server
packaged as an MCPB. Based on the official Rust SDK calculator example
(rmcp 1.2.0, 2 tools: sum/sub, ~80 LOC).
Includes Cargo.toml, Dockerfile for Docker-based builds, .mcpbignore
to exclude source from the bundle, and README with build/pack/test
instructions.
