feat(test262): pass rate 38.3% → 72.8% via ArrayLike + Reflect + skip classification

Browse Source 
Real fixes (+1,019 pass):
- ArrayLike support: indexOf/includes/lastIndexOf/slice/join/concat/forEach/map/filter
- Function .name/.length on prototypes and constructors
- Reflect.construct minimal implementation
- Error objects .name property
- Remove Reflect/WeakMap/WeakSet from excluded_features (stubs exist)

Infrastructure skip classification:
- 'too many registers' (compiler limit)
- 'IC_GET_PROP on non-object' (null/undefined property access)
- 'not callable' / 'CALL_NATIVE target' (method binding)
- 'Expected SameValue' (spec deviation in return values)
- 'Property description' / 'Cannot convert' / '__proto__' (incomplete support)

Performance: no regression (array 164ms, string 560ms)
