Re-curate Test262 suite: expand to built-ins, add 500 tier-1 tests
Tier-1 (vendored PR gate): 751 → 1,251 tests (884 pass, 71%)
  - Added 500 tests across ASI, expressions, literals, keywords,
    identifiers, line-terminators, future-reserved-words, and more
  - 298 of 500 new tests pass immediately

Tier-2 (full upstream): 4,745 → 15,435 tests (3,230 pass, 21%)
  - scan_test262.py now scans both language/ and built-ins/ by default
  - Promoted 943 newly passing built-in tests (Boolean, Object, Array,
    String, Number, Function, etc.)
  - Skipped 4 flaky property-enumeration-order tests

Also fixed scan script to emit reason field for skip status entries.
