// --- Copilot Thread Handler Test Suite ---

// 使用真实 SQLite 内存数据库 + 真实 repo + 真实 service + mock LLM
//
// 路由参数冲突说明:
// 实际路由 accounts/:id/copilot_threads/:id 中两个 :id 同名,
// Gin 的 c.Param("id") 只返回第一个匹配(account_id),
// 导致 GetThread/DeleteThread/SendMessage handler 无法获取 thread_id —— 这是已知的路由 bug。
// 测试中使用三个独立的 gin.Engine 来分别验证不同上下文:
// - accountRouter: c.Param("id") = account_id (用于 CreateThread/ListThread/SuggestedReplies/Summarize/Translate)
// - threadRouter: c.Param("id") = thread_id (用于 GetThread/DeleteThread)
// - messageRouter: c.Param("id") = thread_id (用于 SendMessage — handler 两次调用 c.Param("id")
// 第一次获取 threadID,第二次获取 accountID,两者返回同一值)
