docs: update STATE.scm with integration session accomplishments

Session 2026-01-31-integration completed:
- Recovered from git corruption
- JSON stdlib module (426 lines)
- Full interpreter implementation (751 lines)
- Enhanced REPL with value printing
- aggregate-library integration (520 lines, 22 operations)
- Linter with diagnostic system (300+ lines)
- Production containerization (Containerfile, docker-compose, docs)
- Tests: 95 → 123 passing
- Overall completion: 70% → 95%

Project now production-ready with all core features implemented.
