[Bug] Computer Use MCP cannot switch between macOS Spaces (virtual desktops)

Bug Report

Note: Filed via gh because /feedback is broken — see #41363.

Description

Computer Use MCP's screenshot tool only captures the current macOS Space. When an application is on a different Space (virtual desktop), there is no way to switch to it. switch_display only handles physical monitors, not Spaces.

Steps to Reproduce

1. Open an app (e.g., Notes) on macOS Space/Desktop 2
2. Have Claude Code running on Space/Desktop 1
3. Grant Computer Use access to Notes — succeeds
4. Take a screenshot — shows Space 1, not where Notes is
5. Try switch_display — only works for physical monitors, not Spaces
6. No way to swipe between Spaces without systemKeyCombos

Expected Behavior

Either:

• screenshot should capture the Space where the granted app is visible
• Or provide a switch_space tool to navigate between virtual desktops
• Or systemKeyCombos should be documented as required for multi-Space workflows

Actual Behavior

Dead end. App is granted, running, and visible on another Space, but Computer Use can't see or reach it.
