🤖 feat: make immersive review mode more prominent

[ibetitsmike]

Summary

Makes immersive review mode more discoverable by adding a text label to the toggle button and a new "Immersive review" action in the workspace header's "More actions" dropdown.

Background

The immersive review toggle is currently icon-only (Maximize2 / ArrowLeft) — easy to miss. The only other entry point is the Shift+I keyboard shortcut or a touch-only menu item. This change surfaces the feature for all users.

Implementation

1. ReviewControls — Added "Review" / "Exit" text label next to the existing icon toggle
2. events.ts — Added OPEN_REVIEW_IMMERSIVE custom event (mirrors existing touch event pattern)
3. WorkspaceActionsMenuContent — Added "Immersive review" button with Shift+I shortcut, visible for all non-mux-help workspaces
4. RightSidebar — Added event listener mirroring the existing touch review handler
5. WorkspaceMenuBar — Wired event dispatch and passed callback to the menu content
