refactor: upgrade to Go 1.26 and modernize code idioms

- Replace `interface{}` with `any` type alias across all packages - Use built-in `min()`/`max()` for parameter clamping - Use `slices.SortFunc`, `slices.Min`, `slices.Max` for cleaner code - Use `strings.Cut()` for simpler string parsing in auth middleware - Use `errors.Is()` for proper error comparison in handlers - Update dependencies: golang.org/x/image 0.37.0 -> 0.38.0 - Add Wire code generation guidelines to ARCHITECTURE.md - Disable Go cache in CI build workflow

+## 11. Wire 生成的代码规范
+
+### 11.1 禁止直接修改生成的文件
+
+以下文件由 Wire 工具自动生成，**禁止直接修改**：
+
+- `cmd/server/wire_gen.go`
+- `cmd/server/wire.go` 中的 Provider 函数签名由 Wire 维护
+
+如果需要修改这些文件：
+1. **修改源文件**（如 `wire.go` 中的结构）
+2. **运行 `wire` 命令**重新生成
+
+### 11.2 正确的修改流程
+
+```bash
+# 1. 修改 wire.go 或 wire/*.go
+# 2. 运行 wire 重新生成
+go run -mod=mod github.com/google/wire/cmd/wire ./cmd/server
+```
+
+### 11.3 Provider 依赖添加
+
+新增依赖时，必须同步修改：
+
+1. `wire/service.go` 中的 Provider 函数
+2. `wire/handler.go` 中的 Handler Provider 函数
+3. `cmd/server/wire.go` 中的 `ProvideRouter` 函数
+4. `wire/repository.go`（如需新增 Repository）
+5. 重新运行 `wire ./cmd/server` 生成 `wire_gen.go`
+
+### 11.4 生成文件识别
+
+```
+// Code generated by Wire. DO NOT EDIT.
+//go:generate go run -mod=mod github.com/google/wire/cmd/wire
+//go:build !wireinject
+```
+
+带以上标记的文件均为自动生成文件。
