feat: remove db modify in switch command

@@ -47,6 +47,7 @@ Codex home 的解析顺序：
 - `cdxs alias remove <别名或账号>`：删除指定账号的别名。
 - `cdxs switch`：不带参数时自动选择可用配额最优的账号。
 - `cdxs switch <账号或别名>`：切换到指定账号，OAuth 和 API Key 账号都可通过 alias 切换。
+- `cdxs switch -f <账号或别名>`：切换账号并同步 Codex resume 会话的 provider 状态；普通 `switch` 不修改会话数据库。
 - `cdxs switch A --model <model> --effort <effort> --name OpenAI`：切换时更新该账号默认模型、思考程度；`--name` 仅用于 API 模式的 provider name。
 - `cdxs exec <账号> -- --model gpt-5 "hello"`：用指定账号运行 `codex exec`。
 - `cdxs exec <home> --home --temp -- --model gpt-5 "hello"`：基于指定受管 home 建立一次性临时 `CODEX_HOME` 后运行 `codex exec`。
