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
