fix(ci): 使用预处理的小写 owner 替代 lower 函数

GoReleaser 不支持 lower 模板函数，改为：
- 在 GitHub Actions 中预处理小写 owner
- 传递 GITHUB_REPO_OWNER_LOWER 环境变量给 GoReleaser

+## Antigravity Support
+
+Sub2API supports [Antigravity](https://antigravity.so/) accounts. After authorization, dedicated endpoints are available for Claude and Gemini models.
+
+### Dedicated Endpoints
+
+| Endpoint | Model |
+|----------|-------|
+| `/antigravity/v1/messages` | Claude models |
+| `/antigravity/v1beta/` | Gemini models |
+
+### Claude Code Configuration
+
+```bash
+export ANTHROPIC_BASE_URL="http://localhost:8080/antigravity"
+export ANTHROPIC_AUTH_TOKEN="sk-xxx"
+```
+
+### Hybrid Scheduling Mode
+
+Antigravity accounts support optional **hybrid scheduling**. When enabled, the general endpoints `/v1/messages` and `/v1beta/` will also route requests to Antigravity accounts.
+
+> **⚠️ Warning**: Anthropic Claude and Antigravity Claude **cannot be mixed within the same conversation context**. Use groups to isolate them properly.

+## 简易模式
+
+简易模式适合个人开发者或内部团队快速使用，不依赖完整 SaaS 功能。
+
+- 启用方式：设置环境变量 `RUN_MODE=simple`
+- 功能差异：隐藏 SaaS 相关功能，跳过计费流程
+- 安全注意事项：生产环境需同时设置 `SIMPLE_MODE_CONFIRM=true` 才允许启动
+
+---
+
+## Antigravity 使用说明
+
+Sub2API 支持 [Antigravity](https://antigravity.so/) 账户，授权后可通过专用端点访问 Claude 和 Gemini 模型。
+
+### 专用端点
+
+| 端点 | 模型 |
+|------|------|
+| `/antigravity/v1/messages` | Claude 模型 |
+| `/antigravity/v1beta/` | Gemini 模型 |
+
+### Claude Code 配置示例
+
+```bash
+export ANTHROPIC_BASE_URL="http://localhost:8080/antigravity"
+export ANTHROPIC_AUTH_TOKEN="sk-xxx"
+```
+
+### 混合调度模式
+
+Antigravity 账户支持可选的**混合调度**功能。开启后，通用端点 `/v1/messages` 和 `/v1beta/` 也会调度该账户。
+
+> **⚠️ 注意**：Anthropic Claude 和 Antigravity Claude **不能在同一上下文中混合使用**，请通过分组功能做好隔离。

+// 软删除特性：
+//   - 删除操作不会真正删除数据库记录，而是设置 deleted_at 时间戳

+//   - 通过 SkipSoftDelete(ctx) 可以绕过软删除过滤器，查询或真正删除记录
+//
+// 实现原理：
+//   - 使用 Ent 的 Interceptor 拦截所有查询，自动添加 deleted_at IS NULL 条件
+//   - 使用 Ent 的 Hook 拦截删除操作，将 DELETE 转换为 UPDATE SET deleted_at = NOW()
+//
+// 使用示例：
+//
+//	func (User) Mixin() []ent.Mixin {
