cimery Sprint 1 — Rust 워크스페이스 + 전 계층 파이프라인

8개 크레이트 구현, cargo test 32개 전부 통과:
- core: Mm/M 단위 newtype, UnitExt 리터럴, FeatureError
- ir: GirderIR + 전 단면 파라미터(PSC-I/U/SteelBox/PlateI) serde JSON
- dsl: Girder builder + 검증 (경간 범위·count·spacing)
- kernel: GeomKernel trait + StubKernel (box mesh, AABB)
- incremental: dirty-tracking IncrementalDb (salsa 업그레이드 경로 주석)
- evaluator: 상태 없는 IR→kernel 브리지
- usd: USDA 1.0 텍스트 익스포트 (CimeryBridgeAPI·GirderAPI schema)
- viewer: wgpu 22 + winit 0.30 컬러 삼각형 (Sprint 1 proof-of-concept)

Sprint 2 다음 단계:
- opencascade-rs로 StubKernel 교체 (실제 PSC-I sweep)
- viewer에서 Girder Mesh 렌더 + 카메라 orbit
