[FEATURE]: opencode:// protocol handler to support cmds and args #6009

Describe the enhancement you want to request

It would be nice if the Desktop app supported opencode://<cmd>?...args

I'm selfishly thinking about how trivial this is on the linux side with .desktop files by using the mimetype field.

I guess to support this, there needs to be a bunch of work in both the Desktop App and the Cli App
