Pull request overview

Adds a new “clean window snip” capture mode that can be triggered via a configurable global hotkey and from the tray menu, captures the window under the cursor, and opens it in the overlay with a beautified (padded + shadow) presentation.

Changes:

• Add new persisted setting + settings UI/shortcuts UI to configure a “Clean window snip” hotkey.
• Add a new global hotkey event and tray menu entry to trigger clean window snips.
• Introduce window-under-cursor capture (PrintWindow with screen-capture fallback) and a new overlay session mode to preserve behavior for this flow.
