Hope to add a new coding switch button in the status bar

It is not convenient to switch codes in a session. You need to exit the current session and reconnect it to take effect.
Hope to add a new coding switch button in the status bar and support hot validation, just like xshell.
THANK YOU.

The issue names no files, tests, or entry points. Start by locating the session encoding controls and status-bar implementation, then trace how encoding changes currently require reconnecting. Done means a status-bar switch and hot validation change the active session without leaving or reconnecting it.
