 * SMI-595: extracted from `SecurityScanner.exec.ts` (originally built there
 * under SMI-5359 Wave 4.2 for *content* obfuscation detection) so the
 * name-agnostic folding primitives can be reused for *skill-name* typosquat
 * comparison (`typosquat.ts`) without coupling it to the code-execution /
 * obfuscated-directive detectors. Pure extraction — no behavior change:
 * `SecurityScanner.exec.ts` re-imports these symbols and its own test suite
 * (`SecurityScanner.exec.test.ts`) passes unchanged.
