Rust 크레이트를 루트로 이동

맥락:
- GUI 이식 전에 Rust crate와 proto schema 위치를 Python package 내부에서 분리한다.
- Cargo 작업, IDE 인식, 빌드 산출물 관리를 루트 구조에 맞춘다.

변경:
- rust_core를 rust/lost-cities-core로 이동하고 proto/lost_cities.proto를 루트 proto 디렉터리로 옮겼다.
- Rust build.rs, Python Rust backend, Rust parity 테스트의 경로를 새 위치로 수정했다.
- Python package-data에서 Rust crate와 proto 항목을 제거하고 README/port notes를 갱신했다.

확인:
- uv sync --extra gui --reinstall-package coolrl-lost-cities
- uv run pytest tests/games/classic
- uv run lost-cities-classic
