//! Development tool: emit the Ruby probe plan for arbitrary files so the
//! position sweep (`scripts/ruby-position-sweep.rb`) can check every plan key
//! against what Ruby's `Coverage` module reports for the same source.
//!
//! Usage: `cargo run -p supercov-engine --example ruby_plan -- FILE...`
//! Prints one JSON object: `{ "<path>": { "edits", "branches", "methods",
//! "lines", "cases", "parseError" } }`.
