/**
 * Tests for fs-helpers.ts (3.0.8 consolidation).
 *
 * Covers every helper's happy path, missing-file fallback, and
 * corrupt-input fallback. Isolates all disk I/O under a `mkdtempSync`
 * temp dir so the real `~/.totalreclaw/` is never touched.
 *
 * Run with: npx tsx fs-helpers.test.ts
 *
 * TAP-style output, no jest dependency.
