为统一前后端代码规范与质量，前端引入 ESLint + Prettier，后端在 Spotless 之外新增 Checkstyle 与 SpotBugs，检查接入构建与打包流程并失败即阻断，同时一次性整改全部存量告警，检查范围为后端主源码与前端源码。

变更内容：
- 前端新增 ESLint（flat config）与 Prettier 配置及 lint / lint:fix / format / format:check 脚本，并新增对应开发依赖
- 后端 build.gradle 应用 checkstyle 与 com.github.spotbugs 插件，新增 gradle/checkstyle/checkstyle.xml、suppressions.xml 与 gradle/spotbugs/exclude.xml
- 新增 Gradle frontendLint 任务并作为 frontendBuild 前置，新增 lint 聚合任务（Spotless + Checkstyle + SpotBugs + 前端 ESLint）
- 修复后端 Checkstyle 1 处（补花括号）与 SpotBugs 17 处（getParent() 判空、拆装箱冗余、异常捕获与日志、volatile 同步等），并按设计豁免值对象引用暴露等告警
- 修复前端规则问题（未使用变量、无意义赋值、v-for key、v-html 安全提示）并格式化存量文件
- README 补充依赖安装、代码检查与打包说明

说明：
- SpotBugs 工具版本固定为 4.8.6，规避其 BCEL 与 Spring Boot BOM 选定 commons-lang3 3.14.0 的 NoSuchMethodError
- 检查范围仅主源码，src/test/ 本地测试不纳入 Checkstyle/SpotBugs
- 前端格式化统一为无分号、单引号、行宽 120、LF，与 .gitattributes 保持一致

 ## 快速开始
 
-前置条件：JDK 21（Temurin）、Node.js。
+前置条件：JDK 21（Temurin，含编译工具链与 jpackage）、Node.js（含 npm）。
+
+> 首次构建或运行需联网：Gradle 会下载发行版与 Maven 依赖，前端会 `npm install` 安装依赖。使用 wrapper（`./gradlew` / `gradlew.bat`）可自动获取所需 Gradle 版本。
 
 ```bash
+# Windows 用 gradlew.bat，Linux/macOS 用 ./gradlew
 # 后端（默认 8080，接口文档 http://localhost:8080/doc.html）
-gradlew.bat bootRun
+./gradlew bootRun
 
-# 前端（默认 5173）
-cd frontend && npm run dev
+# 前端（默认 5173，/api 由 Vite 代理到 8080）
+cd frontend && npm install && npm run dev
 ```
 
 数据库无需预先准备：启动后在页面按引导选择 SQLite（本地文件，零配置）或 MySQL，保存后立即生效并自动建表；配置持久化于 `config/database.json`。
 
+## 代码检查
+
+- 后端：`./gradlew lint`（Spotless + Checkstyle + SpotBugs）。
+- 前端：`cd frontend && npm run lint`（ESLint；`npm run lint:fix` 自动修复，`npm run format` 用 Prettier 格式化）。
+- `bootJar` / `bootGuiJar` 会先执行后端检查与前端 ESLint，检查不通过则中断打包。
+
 ## 构建与打包
 
 ```bash
-gradle bootJar bootGuiJar     # 普通 jar + 带 GUI 启动器的 jar，产物在 build/libs/
-gradle jpackageAppImage       # 免安装应用（普通 + GUI），产物在 build/jpackage/
+./gradlew bootJar bootGuiJar   # 普通 jar + 带 GUI 启动器的 jar（内嵌前端），产物在 build/libs/
+./gradlew jpackageAppImage     # 免安装应用（普通 + GUI），产物在 build/jpackage/
 ```
 
+- 打包前会先安装前端依赖并构建前端产物，再一并打入 jar，无需手动 `npm run build`。
 - GUI jar 内嵌前后端与跨平台 JavaFX，单文件即可运行；配置与日志默认落在 jar 所在目录，可用 `--home=<目录>` 或环境变量 `LEDGERLY_HOME` 指定。
 - app-image 自带运行时、免安装，但只能为**当前操作系统**生成。
-
-> 更详细的目录结构、启动器、jpackage、图标与开发环境说明见 `AGENTS.md`。
