/**
 * Shared input-escaping helpers used when generating JavaScript code that
 * embeds user-supplied strings (selectors, text, hash routes, etc.).
 *
 * Why centralized:
 * - Each command module previously had its own ad-hoc validation. Centralizing
 *   prevents drift and makes it easy to audit the "string -> JS literal" path.
 *
 * Note: the heavy-weight DOM-analysis JS generators stay in
 * `src/utils/electron-commands.ts` and `src/utils/electron-input-commands.ts`
 * for now — Phase 7 may consolidate them, but Phase 1 is structural only.
