/**
 * Compute the deterministic mutant id for an edit.
 *
 * The id is the lowercase hex SHA-256 digest of a canonical encoding of
 * `{ fileName, range, replacement }`. It is a pure function of those three
 * inputs: identical inputs always yield an identical id, and any change to file
 * name, span, or replacement text yields a different id. The ` ` field
 * separator cannot appear in source paths or JS source text, so distinct field
 * tuples can never collide by concatenation ambiguity.
 *
 * @param input The edit to identify. Only `fileName`, `range`, and `replacement`
 *   are read; other {@link Replacement} fields are ignored by design.
 * @returns A 64-character lowercase hex string — the stable mutant id.
