refactor(phase-a): remove Cranelift/JIT backend legacy code (~373 lines)
Phase A cleanup - Safe deletions with zero risk: ## Deleted Files (6 files, 373 lines total) 1. Cranelift/JIT Backend (321 lines): - src/runner/modes/cranelift.rs (45 lines) - src/runner/modes/aot.rs (55 lines) - src/runner/jit_direct.rs (152 lines) - src/tests/core13_smoke_jit.rs (42 lines) - src/tests/core13_smoke_jit_map.rs (27 lines) 2. Legacy MIR Builder (52 lines): - src/mir/builder/exprs_legacy.rs - Functionality inlined into exprs.rs (control flow constructs) ## Module Reference Cleanup - src/backend/mod.rs: Removed cranelift feature gate exports - src/runner/mod.rs: Removed jit_direct module reference - src/runner/modes/mod.rs: Removed aot module reference - src/mir/builder.rs: Removed exprs_legacy module ## Impact Analysis - Build: Success (cargo build --release) - Tests: All passing - Risk Level: None (feature already archived, code unused) - Related: Phase 15 JIT archival (archive/jit-cranelift/) ## BID Copilot Status - Already removed in previous cleanup - Not part of this commit Total Reduction: 373 lines (~0.4% of codebase) Next: Phase B - Dead code investigation Related: #phase-21.0-cleanup Part of: Legacy Code Cleanup Initiative
