refactor(phi): Phase 25.1q - PhiMergeHelper unified PHI insertion
**Changes**:
1. Created phi_merge.rs - Unified PHI insertion helper
- PhiMergeHelper struct for Conservative PHI strategy
- merge_variable() - single variable merging
- merge_all_vars() - batch variable merging
- 280 lines of well-documented, reusable logic
2. Refactored phi.rs merge_modified_vars
- Use PhiMergeHelper::merge_all_vars() instead of inline logic
- Reduced from ~80 lines to ~15 lines (81% reduction!)
- Eliminated PHI insertion duplication
**Benefits**:
- Single source of truth for PHI insertion logic
- Improved code clarity (Box-First theory applied)
- Foundation for future loop PHI unification
- Easy to test and maintain
**Testing**:
✅ mir_stage1_using_resolver_full_collect_entries_verifies passes
✅ mir_stage1_using_resolver_min_fragment_verifies passes
✅ Phase 25.1c/k SSA fix preserved
✅ MIR correctness verified
**Code Reduction**:
- Phase A-1: 25 lines (Conservative unification)
- Phase A-2: 65 lines (PhiMergeHelper)
- **Total: 90 lines reduced** (36% of 215 target!)
