Visual indication for choose-file mode

[Tyarel8]

yazi --debug output

Please describe the problem you're trying to solve

When using the --chooser-file option (#69), there is no visual indication anywhere in the UI that this mode is active. While not a critical feature or anything, I think it is good UX to have an indication that this mode is active since it completely changes how the open command works and you wouldn't know it from inside yazi.

Would you be willing to contribute this feature?

• Yes, I'll give it a shot

Describe the solution you'd like

I don't have anything specific in mind, it could be a title at the top, an icon in a corner somewhere, having the theme change some color when this mode is active, etc.

Additional context

No response

I'm not sure where to display it. Instead of directly adding it, I'd prefer to provide an API to implement it, so users can just paste a few lines of Lua code into their init.lua when they need it, kind of like the tips in there (https://yazi-rs.github.io/docs/tips#username-hostname-in-header and https://yazi-rs.github.io/docs/tips#user-group-in-status).
