fix(loop): resolve B-13 by implementing runtime freeze snapshot and dual-root isolation
- Add Stage 2 runtime freeze snapshot at run_loop.sh bootstrap to prevent in-flight tooling mutations
- Implement dual-root architecture separating code execution (frozen snapshot) and workspace state (real repo)
- Ensure original argv preservation and safe cleanup of freeze directories in exit traps
- Add 5 regression guards in tests/test_o3_scoped_guard.py (271/271 PASS)
- Update IMPROVEMENTS.md, VERSIONS.md, and include peer review report
