Fixes from PR #3mhnjr6d5v32x (which cannot be cleanly merged due to duplicate base commit).

Changes #

  • parseInt: Default radix from 10 → 0 (auto-detect), so parseInt("0xFF") returns 255
  • array_concat: Use array_length_exists() instead of arg_len > 0 to correctly spread empty arrays ([1].concat([]) → [1] not [1, []])
  • Dead code: Remove unused obj_proto parameter from init_error_constructors and make_error_subclass_proto

Implements issue 3mhn3mu7azr25
