tomoaki 2da730de35 refactor(cleanup): Phase 285A1 Post-Implementation Cleanup
Code quality improvements after Phase 285A1 implementation:

**Task 1: Dead Code Cleanup**
- Removed unnecessary #[allow(dead_code)] from emit_weak_load()
- Function is actively used in weak_to_strong() method handler

**Task 2: Unused Import Removal (cargo fix)**
- edgecfg/api/mod.rs: Removed seq, if_, loop_, cleanup, verify_frag_invariants
- pattern3.rs: Removed BinaryOperator
- pattern2/api/mod.rs: Removed PromoteStepResult
- jump.rs: Removed EffectMask, Span
- Result: 6 unused imports eliminated

**Task 3: Deprecated Pattern Removal**
- Fixed 4 PlanKind::LoopWithPost deprecated warnings
- Updated to Phase 142 P0 architecture (statement-level normalization)
- Files: normalized_shadow_suffix_router_box.rs, routing.rs,
  execute_box.rs, plan.rs
- Removed 2 deprecated tests: test_loop_with_post_*

**Task 4: WeakFieldValidatorBox Boxification**
- Extracted weak field validation logic into dedicated Box
- New file: src/mir/builder/weak_field_validator.rs (147 lines)
- fields.rs: 277 → 237 lines (-40 lines, -14.4%)
- Added 5 unit tests for validation logic
- Follows Phase 33 boxification principles (single responsibility,
  testability, reusability)

**Metrics**:
- Code reduction: -40 lines in fields.rs
- Test coverage: +5 unit tests
- Warnings fixed: 4 deprecated warnings
- Imports cleaned: 6 unused imports

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 NYASH_JOINIR_VM_BRIDGE_DEBUG=1.

File layout:

  • mod.rs: public surface + shared helpers (naming, error, logging)
  • convert.rs: JoinIR→MIR lowering (functions/blocks/instructions)
  • runner.rs: VM execution entry (run_joinir_via_vm)
  • meta.rs: experimental metadata-aware conversion hooks
  • tests.rs: bridge-specific unit tests (kept local to avoid cross-layer leakage)
