Phase 25.1b type system groundwork - env.* namespace support in Bridge layer
Changes:
- Bridge layer (JSON v0 → MIR):
- Add 'env' as well-known variable in MapVars::resolve()
- Implement env.box_introspect.kind(value) → ExternCall lowering
- Pattern: Method { recv: Method { recv: Var("env"), method: "box_introspect" }, method: "kind" }
- VM/extern fixes:
- Add Arc::from() conversion for env.box_introspect.kind result
- Fix MapBox API usage in extern_functions.rs logging
- Build fixes:
- Comment out missing llvm_legacy/llvm modules in src/backend/mod.rs
- Comment out missing gui_visual_node_prototype in Cargo.toml
- New files:
- lang/src/shared/common/box_type_inspector_box.hako (type introspection API)
Context:
- Enables BoxTypeInspectorBox to query runtime Box types via env.box_introspect.kind
- Required for selfhost MirBuilder type-aware lowering (multi-carrier loops, etc.)
- Part of Phase 25.1b "no fallback" selfhosting strategy
