Release/0.6.4

## 问题背景
在 app 启动后等待 20s 以上，再手动触发数据库连接时，遇到瞬时网络错误（如 `no route to
host`）会立即失败，用户体感为“没有重试”。

相关讨论与上下文参考：
- https://github.com/Syngnat/GoNavi/pull/294

## 问题描述
此前重试保护逻辑主要以“应用启动窗口（20s）”为边界：
- 启动窗口内：瞬时网络失败会自动重试
- 启动窗口外：即使是瞬时网络失败也不重试
这导致“用户首次手动连接发生在稳定期”时，行为与预期不一致。

## 本地复现关键日志（节选）

## 变更内容
- 调整连接重试判定逻辑：
  - 启动窗口内：保持原有重试预算（最多 4 次）
  - 启动窗口外：若为瞬时网络错误，补充一次保护重试（总计 2 次尝试）
  - 非瞬时错误（如认证失败）在稳定期不重试
- 日志文案泛化，避免“仅启动期”误导：
  - 数据库连接在重试后成功
  - 检测到瞬时网络失败，准备重试连接
## 测试与验证
### 新增/更新单元测试覆盖以下场景：
- 启动期瞬时错误重试并成功
- 稳定期瞬时错误重试一次并成功
- 稳定期瞬时错误持续失败时，仅重试一次后停止
- 稳定期非瞬时错误不重试
- 稳定期重试路径输出重试提示日志
- 启动期瞬时错误失败时使用完整重试预算
### 本地执行：
- go test ./internal/app -run StartupRetry -count=1
- go test ./internal/app -count=1
### 影响范围
- 连接建立重试策略（internal/app/app.go）
- 启动重试相关测试（internal/app/app_startup_connect_retry_test.go）
## 风险与回滚
- 风险：稳定期瞬时网络错误会增加一次重试等待（约 800ms）
- 回滚：可回退本 PR 即恢复“仅启动窗口重试”的旧策略
