Feature Request: Dim Unfocused Zed Window to Improve Focus Management

[rafaelrcamargo]

Add an option to automatically dim the Zed editor window when it loses focus. This would help users visually distinguish between active and inactive windows, reducing distractions during multitasking.

Example

• Toggleable setting in Preferences > Appearance: "Dim unfocused window"
• Adjustable dim intensity (e.g., 20%, 40%, 60% opacity overlay)

Use Case

When switching between Zed and another application (e.g., a browser or terminal), the inactive Zed window would subtly fade, making it easier to identify the active workspace.
