Problem or use case

There is no keyboard shortcut to move between terminals, or between splits within a terminal. You have to click.

Proposed solution

Add four keybinding commands, all gated on terminalFocus:

• terminal.next / terminal.previous: cycle terminals with wrap. Default ctrl+tab / ctrl+shift+tab.
• terminal.focusLeft / terminal.focusRight: focus the terminal to the left/right within the current split, no wrap. Default mod+alt+arrowleft / mod+alt+arrowright (cmd+option+arrow on macOS, ctrl+alt+arrow elsewhere).

Why this matters

The drawer already supports creating (cmd+n), splitting (cmd+d), and closing (cmd+w) terminals from the keyboard. Moving between them requires the mouse.

Smallest useful scope

Just terminal.next / terminal.previous. The split-focus pair could ship separately.

Examples or references

• Ghostty defaults: ctrl+tab / ctrl+shift+tab for tab cycling, cmd+option+arrow for split focus on macOS, ctrl+alt+arrow elsewhere.
• [Feature]: Support vertical terminal split alongside the current horizontal layout #1049 (vertical splits): directional naming chosen here is forward-compatible.

ctrl+tab and cmd+option+arrow are browser-reserved, so these defaults target the desktop app. Not sure on the best way forward for the web variant, currently the user would have to edit their keybindings manually. Would appreciate some feedback here.

Cross-platform note: tested on macOS only.
