Sprint 23/24 — Tauri v2 앱 래핑 + salsa 0.16 증분 쿼리 백엔드

Sprint 23: cimery-app을 Tauri v2 앱으로 전환.
- tauri.conf.json, capabilities/default.json, frontend/index.html 추가
- src/commands.rs: 7개 IPC 커맨드 (launch_viewer, 프로젝트 관리, USD/CSV 익스포트)
- 뷰어 사이드카: std::process::Command 방식 (PATH + exe-dir 탐색)
- release.yml: 3단계 멀티플랫폼 릴리스 워크플로로 교체

Sprint 24: cimery-incremental에 salsa 0.16 백엔드 추가.
- salsa_db.rs: BridgeQueryGroup + SalsaIncrementalDb<K>
- --features salsa-backend 로 활성화 (기본값: 수동 tracking, WASM 안전)
- IR 전 구조체 + Mesh + KernelError에 PartialEq/Eq 추가
- 테스트 20개 전부 통과 (수동 12 + salsa 8)
- cargo check --workspace 0 errors/warnings

기타: viewer/dsl 컴파일 경고 제거, wiki 실행 가이드 추가

 //! cimery-incremental — incremental computation layer.
 //!
-//! ## Sprint 8: manual dirty-tracking (all feature types)
+//! ## 백엔드 선택
 //!
-//! Uses a `HashMap` cache + `HashSet<FeatureId>` dirty set.
-//! Query granularity: **Feature-level** (one dirty entry per Feature instance).
-//! Covers all MVP feature types: Girder, DeckSlab, Bearing, Pier, Abutment.
+//! | Feature flag          | 백엔드                     | 타겟             |
+//! |-----------------------|----------------------------|------------------|
+//! | (없음, 기본값)         | 수동 dirty tracking        | 모든 타겟 (WASM) |
+//! | `salsa-backend`       | salsa 0.16 query group     | 데스크톱 전용    |
 //!
-//! ## Sprint 15 upgrade: all feature types
-//! Extended from Girder-only to full MVP feature set. Same dirty-tracking
-//! pattern applied to every feature kind.
+//! 두 백엔드 모두 동일한 공개 API를 제공한다. 테스트 4층 전부 양쪽에서 통과.
 //!
-//! ## Future upgrade: salsa
+//! ## Sprint 8: manual dirty-tracking
+//! HashMap cache + HashSet<FeatureId> dirty set. Feature 단위 쿼리.
 //!
-//! Will be replaced by [salsa](https://github.com/salsa-rs/salsa)-based queries
-//! once the API is confirmed stable for both WASM (web) and native (desktop)
-//! targets (ADR-002 D). Key design intent preserved:
-//! - Feature unit = salsa query granularity.
-//! - Lazy/reactive: only invalidated features recompute (ADR-002 B).
-//! - Cache is keyed by `FeatureId`; invalidation is triggered by `set_*` calls.
+//! ## Sprint 15: 전 Feature 타입으로 확장
+//! Girder 전용 → 5종 MVP Feature (Girder·DeckSlab·Bearing·Pier·Abutment).
+//!
+//! ## Sprint 24: salsa 0.16 optional backend (ADR-002 D)
+//! `--features salsa-backend`로 활성화. WASM 호환 확인 후 기본값으로 승격 예정.
