Fix screenshot capture on high-DPI displays with Windows scaling

[Copilot]

Screenshots were only capturing partial screen content on laptops with Windows display scaling enabled (125%, 150%, 200%).

Root Cause

SystemInformation.VirtualScreen returns logical pixels while Graphics.CopyFromScreen() operates on physical pixels. On a laptop with 150% scaling:

• VirtualScreen reports 1920×1080 (logical)
• CopyFromScreen expects 2880×1620 (physical)
• Result: Only 67% of screen captured

Changes

• DPI awareness: Call SetProcessDPIAware() to align all coordinate systems to physical pixels
• Screen enumeration: Replace VirtualScreen with Screen.AllScreens and calculate bounds explicitly:

  $screens = [System.Windows.Forms.Screen]::AllScreens
  $left = ($screens | ForEach-Object { $_.Bounds.Left } | Measure-Object -Minimum).Minimum
  $width = ($screens | ForEach-Object { $_.Bounds.Right } | Measure-Object -Maximum).Maximum - $left

• Bounds calculation: Compute total virtual desktop bounds across all monitors for multi-monitor support

The DPI awareness call is wrapped in try-catch since it may already be set by the host process.

in laptop when doing /screenshot it doesnt screenshot the whole screen
