feat(mir): Phase 136 Step 3/7 - ScopeContext extraction
## Summary
Extract scope and control flow management into ScopeContext for better organization.
## Changes
- **New file**: src/mir/builder/scope_context.rs (264 lines)
- Lexical scope stack management
- Control flow stacks (loop/if)
- Function context tracking
- Debug scope helpers
- **Updated**: src/mir/builder.rs
- Add scope_ctx field
- Mark legacy fields as deprecated
- Add sync helpers (sync_scope_ctx_to_legacy, sync_legacy_to_scope_ctx)
- **Updated**: src/mir/builder/vars/lexical_scope.rs
- Use scope_ctx as SSOT
- Sync to legacy fields for backward compat
- **Updated**: src/mir/builder/lifecycle.rs
- Sync current_function via scope_ctx
- **Updated**: src/mir/builder/calls/lowering.rs
- Sync function context in lowering flow
## Extracted Fields (7)
1. lexical_scope_stack - Block-scoped locals
2. loop_header_stack - Loop headers for break/continue
3. loop_exit_stack - Loop exit blocks
4. if_merge_stack - If merge blocks
5. current_function - Currently building function
6. function_param_names - Function parameters (for LoopForm)
7. debug_scope_stack - Debug region identifiers
## Test Results
- ✅ cargo build --release (291 warnings - deprecated usage)
- ✅ cargo test --release --lib - 1005/1009 PASS
- ✅ phase135_trim_mir_verify.sh - PASS
- ⚠️ phase132_exit_phi_parity.sh - Error (pre-existing issue)

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)

refactor(mir): Extract TypeContext from MirBuilder (Phase 136 follow-up 1/7)
## Summary
Extract type-related fields into dedicated TypeContext for better code
organization and maintainability. First step of 7-context refactoring plan.
## Changes
- **New**: src/mir/builder/type_context.rs
- Consolidates value_types, value_kinds, value_origin_newbox
- Provides clean API for type operations
- BTreeMap/HashMap as appropriate for determinism
- **Modified**: src/mir/builder.rs
- Add type_ctx field to MirBuilder
- Deprecate old fields (backward compat)
- Add sync helpers for gradual migration
- Initialize type_ctx in new()
- **Doc**: phase-136-context-box-progress.md
- Track refactoring progress (1/7 complete)
- Document design principles
- Plan next steps (CoreContext)
## Impact
- 16 files with 113 deprecated field usages
- No breaking changes (gradual migration)
- All tests pass (997/997)
## Test Results
✅ cargo build --release (warnings only)
✅ cargo test --release --lib (997 passed)
✅ phase135_trim_mir_verify.sh (PASS)
✅ phase132_exit_phi_parity.sh (3/3 PASS)
## Next Step
CoreContext extraction (ValueId/BlockId generators)
