Keep focus on pointer monitor after workspace switch

[cnharrison]

Summary

• fix the bug where enabling “Move pointer with the focus” causes workspace switches to highlight the window on a monitor whose workspace didn’t change
• reuse the pointer’s monitor/workspace when rebuilding the tree so focus returns to the monitor that actually switched workspaces
• after the workspace switch completes, refocus and warp the pointer back to that monitor so it stays active

Behavior Change

• Before: switching workspaces with pointer warp enabled caused Mutter to revive a static window on another monitor, Forge warped the pointer there, and focus jumped away from the monitor whose workspace you actually changed.
• After: Forge remembers which monitor the pointer belonged to, reorders its window list for that monitor, and re-applies focus (plus pointer warp) back to that monitor when the workspace switch finishes.

Impact

• Multi-monitor users with pointer warping enabled keep focus on the monitor whose workspace they switched to, instead of having it jump to a static secondary display.

Testing

• GNOME 46.3 (Wayland)
• move-pointer-focus-enabled=true
• Switching workspaces keeps focus/pointer on the monitor associated with the new workspace; other monitors no longer steal focus.

It looks like the GH actions failure is due to source code formatting issues:

It looks like prettier doesn't like multiline closures:

Running npm run format and committing should solve the issue.
