feat(llvm/phi): Phase 277 P1 - fail-fast validation for PHI strict mode

## Summary
Implemented fail-fast validation for PHI ordering and value resolution in strict mode.

## Changes

### P1-1: Strict mode for "PHI after terminator"
- File: `src/llvm_py/phi_wiring/wiring.py::ensure_phi`
- Behavior: `NYASH_LLVM_PHI_STRICT=1` → RuntimeError if PHI created after terminator
- Default: Warning only (no regression)

### P1-2: Strict mode for "fallback 0"
- File: `src/llvm_py/phi_wiring/wiring.py::wire_incomings`
- Behavior: Strict mode forbids silent fallback to 0 (2 locations)
  - Location 1: Unresolvable incoming value
  - Location 2: Type coercion failure
- Error messages point to next debug file: `llvm_builder.py::_value_at_end_i64`

### P1-3: Connect verify_phi_ordering() to execution path
- File: `src/llvm_py/builders/function_lower.py`
- Behavior: Verify PHI ordering after all instructions emitted
- Debug mode: Shows "✅ All N blocks have correct PHI ordering"
- Strict mode: Raises RuntimeError with block list if violations found

## Testing
✅ Test 1: strict=OFF - passes without errors
✅ Test 2: strict=ON - passes without errors (no violations in test fixtures)
✅ Test 3: debug mode - verify_phi_ordering() connected and running

## Scope
- LLVM harness (Python) changes only
- No new environment variables (uses existing 3 from Phase 277 P2)
- No JoinIR/Rust changes (root fix is Phase 279)
- Default behavior unchanged (strict mode opt-in)

## Next Steps
- Phase 278: Remove deprecated env var support
- Phase 279: Root fix - unify "2本のコンパイラ" pipelines

refactor(mir): Extract VariableContext from MirBuilder (Phase 136 follow-up 5/7)

## Summary
Extracted variable mapping management into dedicated VariableContext struct,
completing step 5 of 7 in the Context Box refactoring plan.

## Changes
- NEW: src/mir/builder/variable_context.rs (VariableContext struct + helpers)
- Modified: src/mir/builder.rs (added variable_ctx field + sync helpers)
- Updated: phase-136-context-box-progress.md (5/7 progress)

## Extracted Fields
- variable_map: BTreeMap<String, ValueId> → variable_ctx.variable_map

## Key Features
- snapshot/restore for if/loop pattern state management
- JoinIR integration: CarrierInfo::from_variable_map()
- ExitLine contract enforcement (carriers in variable_map)
- NYASH_TRACE_VARMAP debug visualization support

## Design Clarity
- BindingContext: String → BindingId (binding identity, survives SSA renaming)
- VariableContext: String → ValueId (current SSA values, block-local)
- Both contexts work together for complete variable management

## Tests
- cargo test --release --lib: 1014/1018 passed (4 pre-existing failures)
- phase135_trim_mir_verify.sh: PASS
- Backward compatibility: 100% maintained (deprecated fields synced)

## Progress
Phase 136 Context Extraction: 5/7 complete (71%)
- ✅ Step 1: TypeContext
- ✅ Step 2: CoreContext
- ✅ Step 3: ScopeContext
- ✅ Step 4: BindingContext
- ✅ Step 5: VariableContext (this commit)
- ⏳ Step 6: MetadataContext
- ⏳ Step 7: CompilationContext
