refactor(smoke): Move feature gap tests to integration (Phase 287 P4)

Moved 7 tests requiring unimplemented features or bug fixes:

Parser/Feature gaps:
- forward_refs_2pass: Requires 2-pass parser for forward references
- parser_min_methods_ok: Parser functionality gap

Map functionality gaps:
- map_values_sum_vm: Map.values() iteration bug
- map_len_set_get_vm: Map operations bug

String functionality gap:
- index_substring_vm: StringBox substring/index bug

Array functionality gap:
- array_oob_get_tag_vm: Array out-of-bounds handling

CLI functionality gap:
- argv_multiline_roundtrip: Argv multiline processing bug

Quick profile focuses on core VM/LLVM functionality that is stable.
These tests will be fixed in dedicated feature/bugfix phases.
