docs: update STATE.scm with compiler implementation progress

Track completion of bytecode compiler and VM implementation session.
Overall project progress: 25% → 60%

Components updated:
- VM compiler: 80% complete (src/vm/compiler.rs)
- VM machine: 85% complete (src/vm/machine.rs)
- Parser: 40% (stub implementation)
- Interpreter: 50% (stub implementation)
- Type checker: 30% (stub implementation)
- REPL: 60% (functional but needs expansion)
- Standard library: 75% complete
- ABI/FFI: 100% complete

Next steps documented in COMPILER-ROADMAP.md:
1. Complete parser implementation (all WokeLang syntax)
2. Complete interpreter implementation
3. Implement type checker (Hindley-Milner inference)
4. Extend VM compiler (lambdas, pattern matching, consent blocks)
5. Write comprehensive test suite
