nyash-codex 76a36333c2 feat(joinir): Phase 204 PHI Contract Verifier complete 
Phase 204-3/5/6/7: PHI inputs verification, integration, testing, docs

Implementation:
- verify_phi_inputs_defined(): Conservative sanity checks (ValueId < 100000)
- Integration: All verifiers in verify_joinir_contracts()
- Testing: 821 tests PASS, no regressions

Task Status:
- ✅ 204-1: Design document (phase204-phi-contract-verifier.md)
- ✅ 204-2: PHI dst overwrite detection
- ✅ 204-3: PHI inputs sanity checks
- ⚠️ 204-4: JoinValueSpace region verification (deferred to Phase 205+)
  - Rationale: Requires LoopHeaderPhiInfo extension (4+ files)
  - Alternative: Conservative threshold checks in verify_phi_inputs_defined()
- ✅ 204-5: Integration (verify_joinir_contracts)
- ✅ 204-6: Tests (821 PASS)
- ✅ 204-7: Documentation (phase204 doc + CURRENT_TASK.md)

Verification Coverage:
- ✅ PHI exists (Phase 200-3)
- ✅ PHI dst match (Phase 200-3)
- ✅ PHI dst not overwritten (Phase 204-2) ✨
- ✅ PHI inputs sanity (Phase 204-3) ✨
- ⚠️ PHI inputs DFA (Phase 205+)
- ⚠️ ValueId regions (Phase 205+)

Design Principles:
- Debug-only (#[cfg(debug_assertions)])
- Fail-Fast (panic on violation)
- Zero cost in release builds

Files Modified:
- src/mir/builder/control_flow/joinir/merge/mod.rs (+115 lines)
- src/mir/builder/control_flow/joinir/merge/exit_line/reconnector.rs (1 line)
- docs/development/current/main/phase204-phi-contract-verifier.md (updated)
- CURRENT_TASK.md (Phase 204 complete)

Success Criteria: 4/5 met (1 deferred with rationale)
