Initial commit: reorganized source tree

- backend/: 13 Maven modules (cw-elevator-application, cloudwalk-cloud, intelligent-cwoscomponent, ninca-crk, etc.)
- frontend/: 4 Vue projects (elevator-front, cwos-portal, alarm-front, front_acs) + decompiled + scripts
- scripts/: build, test-env, tools (Docker Compose, service templates, API parity)
- docs/: AGENTS.md, superpowers specs, architecture docs
- .gitignore: standard Java/Maven exclusions

Moved from legacy maven-*/ root layout to backend/ organized structure.

+## WHERE TO LOOK
+
+| Task | Location | Notes |
+|------|----------|-------|
+| 启动入口 | `ninca-qk-alarm-app-starter/.../AlarmApplication.java` | Spring Boot 主类 |
+| Pom 配置 | `pom.xml` / `ninca-qk-alarm-app-starter/pom.xml` | 父 POM 含 jacoco 配置 |
+
+## CONVENTIONS
+
+- JDK 8
+- P3C Eclipse Formatter（`docs/style/alibaba-eclipse-codestyle.xml`）
+- `jacoco-maven-plugin` 代码覆盖率
+- `formatter-maven-plugin` 配置在父子 POM 中
+
+## NOTES
+
+- V1 反编译参考：`artifacts/decompiled/trees/ninca-qk-alarm-app-V2.9.2_20210730.jar.src/`
+- 当前迭代中此模块非主力目标，仅需保持接口兼容
