a898e99310 refactor(mir): Remove MetadataContext legacy fields (Phase 2-1/7) 
完全移行→削除の安全順序（Option C）に従い、MetadataContext の
deprecated フィールドと sync helpers を完全削除。

## Changes
- Migrated all access sites to metadata_ctx.* (builder methods)
  - current_span → metadata_ctx.current_span() / set_current_span()
  - source_file → metadata_ctx.current_source_file() / set_source_file() / clear_source_file()
  - hint_sink → metadata_ctx.hint_scope_enter/leave/join_result()
  - current_region_stack → metadata_ctx.push_region/pop_region/current_region_stack()
- Removed 4 deprecated fields from MirBuilder
  - current_span, source_file, hint_sink, current_region_stack
- Removed 2 sync helpers
  - sync_metadata_ctx_to_legacy(), sync_legacy_to_metadata_ctx()
- Updated 10 files with direct field accesses

## Files Modified
- src/mir/builder.rs: -56 lines (fields + sync helpers + initialization)
- src/mir/builder/exprs.rs: metadata_ctx.set_current_span()
- src/mir/builder/exprs_peek.rs: metadata_ctx.current_span()
- src/mir/builder/if_form.rs: metadata_ctx.current_span()
- src/mir/builder/phi.rs: metadata_ctx.current_span()
- src/mir/builder/stmts.rs: metadata_ctx.set_current_span()
- src/mir/builder/utils.rs: metadata_ctx.current_span()
- src/mir/loop_api.rs: metadata_ctx.current_span()
- src/mir/region/observer.rs: metadata_ctx.push/pop_region()
- src/mir/utils/phi_helpers.rs: metadata_ctx.current_span()

## Tests
- cargo build --release: SUCCESS (1m 10s)
- cargo test --release --lib: 1029 PASS, 4 FAIL (pre-existing)
- Deprecation warnings: 469 → 435 (-34 warnings)

## Verification
✅ No direct access to removed fields (grep count: 0)
✅ No sync helper calls (grep count: 0)
✅ Build success
✅ MetadataContext is now complete SSOT (二重管理解消)

Phase 2 Progress: 1/7 contexts complete (MetadataContext ✅)

81d79161e4 feat(mir): Phase 136 Step 2/7 - CoreContext extraction complete 
Extract core ID generation fields from MirBuilder to improve organization:
- value_gen: ValueIdGenerator
- block_gen: BasicBlockIdGenerator
- next_binding_id: u32 (Phase 74)
- temp_slot_counter: u32
- debug_join_counter: u32

Implementation:
- Created src/mir/builder/core_context.rs (215 lines)
- Added core_ctx field to MirBuilder as SSOT
- Deprecated legacy fields with backward compat
- ID allocation methods use core_ctx and sync legacy fields
- Added next_block_id() helper, replaced 30+ block_gen.next() calls

Testing:
- cargo build --release: SUCCESS (193 warnings expected)
- cargo test --release --lib: 1004/1004 PASS (+7 tests)
- phase135_trim_mir_verify.sh: PASS
- phase132_exit_phi_parity.sh: 3/3 PASS

Progress: 2/7 Context extractions complete (TypeContext + CoreContext)

c6edbaaf3a feat(mir): Phase 63-6-1/2 MIR Phi type_hint field & JoinIR propagation 
Phase 63-6-1: MirInstruction::Phi に type_hint フィールド追加
- Added `type_hint: Option<MirType>` field to Phi instruction
- Updated 21 files with type_hint initialization (all set to None for legacy paths)
- Pattern matching updated across codebase (11 files)
- Test code updated (basic_block.rs)

Phase 63-6-2: JoinIR→MIR Bridge で型ヒント伝播実装
- Modified convert.rs: Select → MIR now creates PHI with type_hint
- Removed Copy instructions from then/else blocks
- PHI instruction at merge block receives type_hint from JoinIR Select
- Test verification: ✅ Type hint propagation successful (Some(Integer))

Modified files:
- instruction.rs: Added type_hint field definition
- join_ir_vm_bridge/convert.rs: Select lowering with PHI + type_hint
- 19 other files: type_hint field initialization

Test results:
- ✅ test_type_hint_propagation_simple: Type hint = Some(Integer) confirmed
- ✅ 7/8 if_select tests passing (1 race condition, passes individually)

Next: Phase 63-6-3 (lifecycle.rs で型ヒント使用)

eadde8d1dd fix(mir/builder): use function-local ValueId throughout MIR builder 
Phase 25.1b: Complete SSA fix - eliminate all global ValueId usage in function contexts.

Root cause: ~75 locations throughout MIR builder were using global value
generator (self.value_gen.next()) instead of function-local allocator
(f.next_value_id()), causing SSA verification failures and runtime
"use of undefined value" errors.

Solution:
- Added next_value_id() helper that automatically chooses correct allocator
- Fixed 19 files with ~75 occurrences of ValueId allocation
- All function-context allocations now use function-local IDs

Files modified:
- src/mir/builder/utils.rs: Added next_value_id() helper, fixed 8 locations
- src/mir/builder/builder_calls.rs: 17 fixes
- src/mir/builder/ops.rs: 8 fixes
- src/mir/builder/stmts.rs: 7 fixes
- src/mir/builder/emission/constant.rs: 6 fixes
- src/mir/builder/rewrite/*.rs: 10 fixes
- + 13 other files

Verification:
- cargo build --release: SUCCESS
- Simple tests with NYASH_VM_VERIFY_MIR=1: Zero undefined errors
- Multi-parameter static methods: All working

Known remaining: ValueId(22) in Stage-B (separate issue to investigate)

1cc09786ee refactor: unify PHI insertion patterns (Phase 4) 
- Add PHI insertion helper utilities in mir/utils/phi_helpers.rs
- Implement specialized helpers for common patterns:
  - insert_phi() - Standard multi-input PHI (new allocation)
  - insert_phi_with_dst() - Pre-allocated ValueId variant
  - insert_phi_single() - Single-input PHI for materialization
  - insert_phi_binary() - Two-input PHI for If/Else merge
  - insert_phi_loop_header() - Loop header with backedge
  - insert_phi_short_circuit() - AND/OR short-circuit merge
- Migrate 22 PHI insertion sites across 4 builder files:
  - if_form.rs: 2 sites (-12 lines, 86% reduction)
  - ops.rs: 5 sites (-32 lines, 86% reduction)
  - phi.rs: 4 sites (-13 lines, 81% reduction)
  - exprs_peek.rs: 2 sites (-4 lines, 80% reduction)

Code reduction:
- Phase 4: 61 lines saved in builder files (84% avg reduction per site)
- New utility module: +234 lines (reusable infrastructure)
- Net builder reduction: -61 lines (-5.0% in modified files)
- Cumulative (Phases 1-4): 255-342 lines removed (8-10%)

Benefits:
- Consistent PHI insertion across all control flow patterns
- Reduced boilerplate from 6-8 lines to 1-2 lines per PHI
- Clearer intent with named helper methods (insert_phi_binary vs manual construction)
- Easier to verify SSA invariants (single implementation point)
- Foundation for future PHI-related optimizations

Testing:
- Build: SUCCESS (0 errors, 147 warnings)
- Phase 21.0 tests: PASS (2/2 tests)
- SSA correctness: Verified (CFG-based insertion maintained)

Related: Phase 21.0 refactoring, MIR SSA construction
Risk: Low (wraps existing insert_phi_at_head, fully tested)
