[Feature] Keyboard shortcut to switch the active host

[Jungwoon]

I use Orca with more than one host (my local Mac plus remote runtimes), and I switch between them many times a day. Right now the only way to change the active host is with the mouse.

I checked the keybinding definitions in 1.4.246. There are 95 bindable actions, but none of them switch hosts or runtime environments, so I can't add a custom binding in the keybindings file either.

Suggestion

• A host palette action (for example host.palette), similar to worktree.palette (⌘J)
• Optional: next / previous host, and "Select Host 1–9", like the existing worktree and tab actions
• All of these exposed in the keybindings file so users can pick their own keys

Thanks for Orca — it's become my daily driver.

I think we need a keyboard configuration page, to address different needs one may have

right now I want to send a line break with ctrl + enter, like other apps, but Orca is Alt+enter
