Publish the first Windows executable release

[AlexMnrs]

Goal

Publish a tested Windows executable so users can try UltraShare without setting up Python manually.

Why this matters

UltraShare is aimed at presenters, streamers, teachers, and remote workers. A downloadable release lowers the barrier for people who are not comfortable cloning a repository or running Python commands.

Suggested steps

• Run the manual workflow: Build Windows executable.
• Download the UltraShare-windows artifact.
• Test UltraShare.exe on Windows 10 or Windows 11.
• Confirm the control panel opens.
• Confirm the overlay frame appears.
• Confirm the window list refreshes.
• Snap a normal application window into the overlay region.
• Move the overlay and confirm the snapped window stays aligned.
• Note any elevated-window or multi-monitor limitations.
• Publish a GitHub Release with the executable and short release notes.

Acceptance criteria

• A GitHub Release exists with UltraShare.exe attached.
• Release notes explain that this is an early Windows build.
• The README links to the release.
• Any known limitations found during testing are documented.
