//! Explicit cross-language call-graph bridge edges.
//!
//! Without an [`InteropEdge`], the call graph resolver never attempts
//! cross-language resolution. This prevents false positives from functions
//! in different languages that happen to share a name.
//!
//! An [`InteropEdge`] maps a [`CallSiteKey`] (caller language, file, function,
//! callee symbol, call ordinal) to a [`FuncKey`] in another language. Ordinal
//! `0` acts as a wildcard matching any call of that name from the given caller.
