Import S-CANVAS source + iter=1~7 lint cleanup

S-CANVAS (Saman Corp.) — DXF + DEM + AI 기반 3D 조감도 생성 엔진.
~24k LOC Python (scanvas_maker.py 7072 LOC GUI + 구조물 파서/빌더 다수).

이 커밋은 7-iter cleanup이 적용된 상태로 import:
- F821 8 + B023 6: 비동기 lambda + except/loop 변수 캡처 NameError
  (Py3.13에서 reproduce 확인된 진짜 버그)
- RUF012 4 + RUF013 1: ClassVar / implicit Optional 명시화
- F811/B905/B904/F401/F841/W293/F541/UP/SIM/RUF/PLR 700+ cleanup/modernization

신규 파일:
- ruff.toml: target=py313, Korean unicode/저자 스타일/도메인 복잡도 무력화
- requirements-py313.txt: pyproj>=3.7, scipy>=1.14, numpy>=2.0.2 (Py3.13 wheel)
- .gitignore: gcp-key.json, 캐시, 백업, 생성 이미지 제외

검증: ruff 0 errors, py_compile 0 errors, import 33/33 OK on Py3.13.13.

+"""파서 결과 → JSON 브리지 (S-CANVAS env 측 generic 헬퍼).
+
+이 모듈은 bpy를 import하지 않으므로 기존 S-CANVAS conda 환경에서 그대로 사용 가능.
+파서가 생성한 dataclass 파라미터(IntakeTowerParams, GateParams, ...)를 JSON으로 직렬화.
+
+사용:
+    # 취수탑
+    from intake_tower_parser import parse_intake_tower
+    from params_to_json import dump_dataclass_to_json
+    p = parse_intake_tower(dxf_paths)
+    dump_dataclass_to_json(p, "intake_params.json")
+
+    # 여수로 수문
+    from gate_parser import parse_gate_dxf
+    from params_to_json import dump_dataclass_to_json
+    p = parse_gate_dxf(plan_dxf, section_dxf)
+    dump_dataclass_to_json(p, "gate_params.json")
+
+이후 Blender 헤드리스로:
+    blender --background --python <builder_bpy>.py -- ^
+        --params <params>.json --blend out.blend --render out.png
