Pull Request Overview

This PR fixes a shell plugin focus issue by implementing a more robust window focus mechanism and increasing delay timing. The changes address Windows' interference with Win+R keyboard shortcuts that were preventing proper focus restoration.

• Increased Task.Delay from 50ms to 1000ms to better handle Windows' Win+R processing
• Added a new BringToForegroundEx method that uses multiple Win32 APIs for reliable window focusing
• Enhanced the focus mechanism to call the new method before setting text box focus

The delay has been increased from 50ms to 1000ms, which is a 20x increase. This significantly impacts user experience by making the application feel unresponsive. Consider a more moderate increase (e.g., 100-200ms) or implement a retry mechanism with shorter delays.

Suggested change

	await Task.Delay(1000);
	Context.API.FocusQueryTextBox();
	// Try to set focus up to 4 times with 50ms intervals (max 200ms)
	for (int i = 0; i < 4; i++)
	{
	await Task.Delay(50);
	Context.API.FocusQueryTextBox();
	}
