Ported type_info($T) into the VM (callBuiltinVm .type_info arm -> new
buildTypeInfo), the inverse of step 7's define: reflect a type INTO a TypeInfo
VALUE built in flat memory (VM-native mirror of legacy reflectTypeInfo).
- Decodes the source type into a tag + members (tagged-union/struct field &
enum variant -> {name, ty}, payloadless variant -> void; tuple -> bare
positional Types), then lays the nested value out bottom-up using layouts
derived from the TypeInfo RESULT type (ins.ty, now threaded into
callBuiltinVm): element array -> {ptr,len} slice -> info struct
(EnumInfo/StructInfo/TupleInfo) -> TypeInfo {tag, payload} tagged union
(reusing step 7's tagged-union write).
- Variant/field names materialize via makeStringValue, extracted from text_of.
- Same backing_type guard as step 7 (bail rather than mis-read the tag).
The ENTIRE metatype surface now runs HANDLED on the VM with ZERO fallback:
0614-0624 + 0632 (0616 field_type folds at lower time). The
define(declare, type_info(T)) round-trips (0619/0622/0623) mint byte-identical
copies on the VM; VM output byte-matches legacy for all. 697/0 both gates + all
unit tests. Remaining VM fallbacks in the comptime corpus are now genuinely
non-metatype emit-time side effects (print/global_addr/compiler_call/inline-asm).
