/**
 * test-all.mjs — Comprehensive test suite for career-ops
 *
 * Run before merging any PR or pushing changes.
 * Tests: syntax, scripts, dashboard, data contract, personal data, paths.
 *
 * Usage:
 *   node test-all.mjs                        # Run all tests
 *   node test-all.mjs --quick                # Skip dashboard build (faster)
 *   node test-all.mjs --only <substring>      # Run ONLY discovered tests/**\/*.test.mjs
 *                                             # files whose path contains <substring>
 *                                             # (e.g. --only providers/themuse).
 *
 *   LOUD WARNING: `--only` runs ONLY discovered tests/ files — every inline
 *   core section above (syntax, scripts, dashboard, data contract, personal
 *   data, paths, etc.) is SKIPPED. A green `--only` run is NOT a green
 *   suite. Always run the full suite (no flags) before pushing.
 *
 * Provider tests live in tests/providers/{name}.test.mjs and are
 * auto-discovered — no registration needed. To add a test for a new
 * provider, create that one file; do not add a section to this file.

// already handled by the old ++maxNum fallback). This one exercises the actual

// (merge-tracker's own header/separator-skip heuristic excludes any row whose
// company/role text happens to contain "Empresa" or "---" — a real Spanish-
// market company name is a realistic trigger), so the naive
// `addition.num > maxNum` check trusted a colliding number as free. The fix
// builds a Set of every number actually on the tracker (independent of that
// heuristic) and refuses to trust a number already in it.
