calc-core vs clincalc vs stedi-rs

Pure clinical calculator engine - scoring logic and result schema shared by the `calc` CLI, the web tools, and downstream hosts. Deliberately a dependency-light leaf crate: serde only, no host application, no async runtime.

Open, auditable clinical calculators: a pure scoring engine plus the `clincalc` CLI in one crate. The engine is a serde-only leaf (build with default-features = false); the default `cli` feature adds the `clincalc` binary.
