refactor: 统一打包命令为 dist 体系，build 仅编译不打包

- build:linux/mac/win → dist/dist:linux/dist:mac/dist:win
- Turbo 任务依赖：desktop#dist:* → server#compile → server#build
- 根目录 bun dist 一条命令完成完整打包流水线
- 更新 AGENTS.md 文档同步命令变更

 ## Production Build Workflow
 
-1. **Build server**: `bun build` in `apps/server` → `.output/`
-2. **Compile server**: `bun compile` in `apps/server` → `out/server-{platform}`
-3. **Copy binary**: Copy the platform-appropriate binary to `apps/desktop/resources/server`
-4. **Package desktop**: `bun build:linux` (or `:mac` / `:win`) in `apps/desktop`
+From monorepo root, run `bun dist` to execute the full pipeline automatically (via Turbo task dependencies):
+
+1. **Build server**: `apps/server` → `vite build` → `.output/`
+2. **Compile server**: `apps/server` → `bun compile.ts` → `out/server-{platform}`
+3. **Package desktop**: `apps/desktop` → `electron-vite build` + `electron-builder` → distributable
+
+The `electron-builder.yml` `extraResources` config reads binaries directly from `../server/out/`, no manual copy needed.
+
+To build for a specific platform explicitly, use `bun dist:linux` / `bun dist:mac` / `bun dist:win` in `apps/desktop`.
