[FEATURE] Add keyboard shortcut for switching between Code sessions in Claude Desktop

Problem Statement

I'm migrating from Claude Code CLI to Claude Desktop's Code feature. In the CLI, my terminal gives me tabs I can cycle through with keyboard shortcuts (e.g., Cmd+Shift+]/Cmd+Shift+[). Claude Desktop already has a session list in the sidebar, but there's no keyboard shortcut to cycle through sessions — I have to click each one with the mouse.

Proposed Solution

Add keyboard shortcuts to cycle through Code sessions in the sidebar (e.g., Cmd+Shift+]/Cmd+Shift+[), matching the convention used by most terminal emulators and browsers for tab switching.

Alternative Solutions

Arrow key navigation within the session list when it has focus would also work.

Priority

Medium - Would be very helpful

Interactive mode

Use Case Example

Coming from the CLI, I'm used to switching between sessions entirely with the keyboard via terminal tab shortcuts. The session list already exists in Claude Desktop's sidebar — it just needs a keyboard-driven way to navigate it.
