Fixed scheme registration & improved installer reliability

Fixed

• Fixed incorrect cursor scheme registration that caused Windows to display "None"
• Prevented Windows from showing the "Replace scheme" prompt after installation
• Improved cursor refresh logic (no logout or reboot required)

Improved

• Cursor scheme now applies automatically without user interaction
• More reliable registry handling
• Cleaner installation flow

Important

• No manual confirmation is required.
• Do NOT click OK or Apply in Mouse Properties — the scheme is already active.
