The LoadItemThumbnail method was invoking the callback from background threads (inside Task.Run), causing bedHistory.Invalidate() to not refresh the menu items correctly on first try. Wrapping the callback in UiThread.RunOnIdle ensures it runs on the UI thread. Fixes MatterHackers#4959
Updates agg-sharp to include the Shift+Click text selection fix.
The default end gcode was missing M140 S0 to turn off the heated bed after a print completes. This caused the bed to remain hot after printing. Added M140 S0 at the beginning of the end gcode to ensure the heated bed is properly turned off. Fixes: MatterHackers#5434
When opening the 'Open Recent' menu for the first time after launch, thumbnails are loaded asynchronously. The original code only invalidated the individual menu item (bedHistory.Invalidate()), but this may not be sufficient to trigger a proper redraw of the submenu contents. This fix adds subMenu.Invalidate() alongside the existing bedHistory.Invalidate() to ensure both the menu item and its parent submenu are properly refreshed when thumbnails are loaded. Fixes: MatterHackers#4959

Description
The LoadItemThumbnail method was invoking the callback from background threads (inside Task.Run), causing bedHistory.Invalidate() to not refresh the menu items correctly on first try.
Fix
Wrapping the callback in UiThread.RunOnIdle ensures it runs on the UI thread, which allows Invalidate() to work correctly and refresh the Open Recent menu items.
Issue
Fixes #4959 - Open Recent does not refresh correctly on first try [$50]
