JoinIR → VM bridge layer
Responsibilities:
- Convert normalized JoinIR modules into MIR for the Rust VM without changing semantics.
- Provide a thin runner helper that executes a JoinIR entry via the VM.
- Host experimental metadata-aware paths (Phase 40-1) behind clearly marked helpers.
Boundaries:
- No new control-flow semantics or heuristics here; this layer only maps structures already normalized by JoinIR.
- Keep type information minimal (MirType::Unknown) and avoid adding inference or guessing.
- Debug/diagnostic output must stay behind
