nyash-codex 99bdf93dfe feat(joinir): Phase 47-A-LOWERING - P3 Normalized→MIR(direct)

Implement full Pattern3 (if-sum) Normalized→MIR(direct) support, completing
the P3 minimal implementation.

Key changes:

1. P3 Shape Detection (shape_guard.rs):
   - Implemented is_pattern3_if_sum_minimal() with structure-based detection
   - Detects P3 characteristics:
     - Has Compare instruction (loop condition)
     - Has Select instruction (conditional carrier update)
     - Has tail call (Call with k_next: None)
     - Reasonable param count (2-4 for i, sum carriers)
   - Handles both JoinInst::Select and Compute(MirLikeInst::Select)
   - Added unit test: test_detect_pattern3_if_sum_minimal_shape ✅

2. P3 Normalization Function (normalized.rs):
   - Implemented normalize_pattern3_if_sum_minimal()
   - Guards: Validates Structured JoinIR + P3 shape detection
   - Phase 47-A minimal: Delegates to P2 normalization (works for simple cases)
   - Updated normalized_dev_roundtrip_structured() integration
   - Returns Result<NormalizedModule, String> for proper error handling

3. Bridge Integration (bridge.rs):
   - Updated normalize_for_shape() to call P3 normalization
   - No changes needed to direct.rs (already handles P3 instructions)

4. Integration Tests (normalized_joinir_min.rs):
   - Added test_phase47a_pattern3_if_sum_minimal_normalization
     - Tests Structured→Normalized transformation
     - Verifies shape detection + normalization succeeds
     - Validates function count and phase correctness
   - Added test_phase47a_pattern3_if_sum_minimal_runner
     - Basic smoke test for P3 fixture validity
     - Verifies 3-function structure and entry point

Benefits:
- P3 now uses Normalized→MIR(direct) pipeline (same as P1/P2)
- Structure-based detection (no name-based heuristics)
- Minimal implementation (delegates to P2 for simplicity)
- Pure additive (no P1/P2 behavioral changes)

Tests: 938/938 PASS (lib), shape_guard P3 test PASS
- test_detect_pattern3_if_sum_minimal_shape ✅
- test_phase47a_pattern3_if_sum_minimal_normalization ✅
- test_phase47a_pattern3_if_sum_minimal_runner ✅

Next phase: Phase 47-B (proper P3-specific normalization, array_filter, multi-carrier)

Design note: This minimal implementation reuses P2 normalization for simplicity.
Proper P3-specific normalization (IfCond, ThenUpdates, ElseUpdates step sequence)
will be implemented in Phase 47-B when needed for more complex P3 patterns.
