chore: release v1.0.39

文件锁在 Windows 上行为不一致，改用绑定本地端口（54317）作为互斥锁，
进程退出时 OS 自动释放，Windows/macOS 均可靠生效。

+## [1.0.39] - 2026-06-15
+
+### 修复
+- 打印预览弹窗：打印完成后自动关闭
+- 打印预览弹窗：打印机列表改为仅显示热敏打印机，无热敏打印机时显示"无打印机可用"并禁用打印按钮
+- 库存列表表格行"打标签"按钮点击无反应
+- Windows/macOS 单实例限制：同一台电脑不允许重复打开多个客户端窗口
+
+## [1.0.38] - 2026-06-15
+
+### 新功能
+- 标签打印新增「打印预览」弹窗，点击打印按钮后可先预览标签内容再确认打印
+- 预览弹窗支持选择打印机（下拉列表），并记住上次选择，下次自动默认
+- 支持对每张标签单独设置打印份数（默认 1 份）
+- 入库单「打标签」支持多张预览：左侧缩略图条可逐张勾选/取消，右侧显示当前选中张的大图
+
+## [1.0.37] - 2026-06-15
+
+### 新功能
+- 库存查询新增「规格」和「系列」筛选，支持多选，按服务端过滤全量数据
+- 库存查询新增「入库时间」列
+- 入库单商品明细将「生产日期」移至主行直接可见，无需展开隐藏区域
+
+### 改进
+- 筛选弹窗重构：顶部搜索框实时过滤、选项列表可滚动、已选项以标签形式置顶显示并可单独取消
+- 筛选图标改为常驻显示，无需鼠标悬停
+
+### 修复
+- 修复商品系列批量导入被截断至 100 条的问题
+
+## [1.0.36] - 2026-06-13
+
+### 修复
+- 修复数据库初始化时 license_key 索引超长导致启动失败的问题
+
+## [1.0.35] - 2026-06-12
+
+### 改进
+- Debug 版本窗口标题增加 [DEBUG] 后缀，便于与正式安装版区分

+# 酒库管理系统 — Gemini 编码规则
+
+## 项目背景
+
+这是一个多租户酒类库存管理系统，Go 后端 + Flutter 前端。
+
+## 强制规则（违反即重写）
+
+### 多租户隔离
+- `shop_id` **永远**从 `middleware.GetShopID(c)` 获取
+- **绝不**从 request body、URL params、query string 读取 shop_id
+- 所有数据库查询必须带 `WHERE shop_id = ?` 条件
+
+### 并发安全
+- 同一事务内读后写必须用 `FOR UPDATE` 锁行：
+  ```go
+  tx.Set("gorm:query_option", "FOR UPDATE").Where(...).First(&model)
+  ```
+- 适用：单号生成、库存扣减、任何 check-then-act 模式
+
+### 代码风格（参考 handler/product.go）
+- Handler 函数签名：`func (h *Handler) ActionName(c *gin.Context)`
+- 统一错误返回：`c.JSON(http.StatusBadRequest, gin.H{"error": "..."})`
+- 成功返回：`c.JSON(http.StatusOK, result)`
+- 所有 DB 操作通过 `h.db`，不直接引用全局变量
+
+### Schema 管理
+- 表结构变更同步修改 `backend/schema/schema.sql`
+- 无单独迁移文件，启动时 AutoMigrate
+- 不为单个字段加新列，用 `custom_fields JSON` 扩展
+
+### 测试规范
+- 测试文件放在同包下：`xxx_test.go`
+- 使用 `testutil/` 下的辅助函数
+- 每个 handler 至少覆盖：正常路径 + 缺少 shop_id 的 403 场景
+
+## 参考文件
+- Handler 模式：`backend/internal/handler/product.go`
+- Model 模式：`backend/internal/model/product.go`
+- 认证中间件：`backend/internal/middleware/auth.go`
+- Schema：`backend/schema/schema.sql`

+# 库存查询「规格」「系列」列头筛选 — UI 变更规范
+
+**变更类型**：简单变更，flutter-coder 可直接实现
+**对应文件**：`client/lib/screens/inventory/inventory_list_screen.dart`
+
+---
+
+## 复杂度判断
+
+复用现有 `FilterableColumnHeader` 组件，实现方式与已有「仓库」列筛选完全一致，无新组件、无新页面、无复杂交互，属于简单变更。
+
+---
+
+## 变更详情
+
+### [UI-001] 新增 State 变量
+
+**位置**：`_InventoryListScreenState` 类顶部，紧跟 `_filterWarehouse` 声明之后
+
+```dart
+Set<String> _filterWarehouse = {};
+Set<String> _filterSpec = {};      // 新增：规格筛选
+Set<String> _filterSeries = {};    // 新增：系列筛选
+```
+
+---
+
+### [UI-002] 派生筛选选项
+
+**位置**：`_buildInventoryTab()` 方法内，`data:` 回调中，紧跟 `warehouseOptions` 和 `filteredItems` 的现有代码之后替换
+
+**现有代码段（第 368-379 行）：**
+
+```dart
+final warehouseOptions = items
+    .map((i) => i.warehouseName)
+    .where((s) => s.isNotEmpty)
+    .toSet()
+    .toList()
+  ..sort();
+final filteredItems = _filterWarehouse.isEmpty
+    ? items
+    : items
+        .where((i) => _filterWarehouse.contains(i.warehouseName))
+        .toList();
+```
+
+**替换为：**
+
+```dart
+final warehouseOptions = items
+    .map((i) => i.warehouseName)
+    .where((s) => s.isNotEmpty)
+    .toSet()
+    .toList()
+  ..sort();
+
+final specOptions = items            // 新增：规格选项
+    .map((i) => i.spec)
+    .where((s) => s.isNotEmpty)
+    .toSet()
+    .toList()
+  ..sort();
+
+final seriesOptions = items          // 新增：系列选项
+    .map((i) => i.series)
+    .where((s) => s.isNotEmpty)
+    .toSet()
+    .toList()
+  ..sort();
+
+// 三个筛选叠加（AND 逻辑）
+final filteredItems = items.where((i) {
+  if (_filterWarehouse.isNotEmpty && !_filterWarehouse.contains(i.warehouseName)) {
+    return false;
+  }
+  if (_filterSpec.isNotEmpty && !_filterSpec.contains(i.spec)) {
+    return false;
+  }
+  if (_filterSeries.isNotEmpty && !_filterSeries.contains(i.series)) {
+    return false;
+  }
+  return true;
+}).toList();
+```
+
+**说明：**
+- 选项数据从当前页已加载的 `items` 派生，客户端筛选，与「仓库」逻辑一致
+- 三个筛选条件为 AND 叠加（同时满足才显示）
+- 空集合（`isEmpty`）视为「不筛选该维度」，等同于全选
+
+---
+
+### [UI-003] 替换「规格」和「系列」列头
+
+**位置**：`columns:` 列表中第 491-494 行（当前为 `const DataColumn`）
+
+**现有代码：**
+
+```dart
+const DataColumn(label: Text('规格')),
+const DataColumn(label: Text('系列')),
+```
+
+**替换为：**
+
+```dart
+DataColumn(
+  label: FilterableColumnHeader(
+    text: '规格',
+    options: specOptions,
+    selected: _filterSpec,
+    onChanged: (v) => setState(() => _filterSpec = v),
+  ),
+),
+DataColumn(
+  label: FilterableColumnHeader(
+    text: '系列',
+    options: seriesOptions,
+    selected: _filterSeries,
+    onChanged: (v) => setState(() => _filterSeries = v),
+  ),
+),
+```
+
+**注意**：移除原来的 `const` 关键字，因为构造函数参数不再是编译期常量。
+
+---
+
+## 视觉规范（无需改动）
+
+`FilterableColumnHeader` 的所有视觉行为保持原样：
+
+| 状态 | 表现 |
+|------|------|
+| 默认（无筛选） | 纯文字列头，无图标 |
+| Hover | 显示半透明 `filter_alt_outlined` 图标（灰色）|
+| 已激活筛选 | 图标变为实心 `filter_alt`（主色 #1565C0）+ 右侧出现 X 清除按钮 |
+| X 按钮点击 | 清空该维度筛选（`onChanged({})` ），无需打开弹窗 |
+| 列头点击图标 | 弹出 `_MultiSelectDialog`（全选/清空 + checkbox 列表 + 取消/应用） |
+
+---
+
+## 受影响范围
+
+- 仅修改 `_InventoryListScreenState` 内部，不涉及 provider、model、API
+- `_buildWarningTab()` 和 `_buildLogTab()` 不受影响
+- 导出 Excel 的 `filteredItems` 自动受益于新筛选逻辑，无需额外改动
+- 窄屏卡片流（`mobileCards`）同样使用 `filteredItems`，筛选效果自动生效
