Release v2.5.4

Fixed

• Patreon Library on Forge. Opening the library no longer hangs for 30 seconds on a blank window. The panel appears instantly with a loading indicator while pack data loads in the background.
• Check for updates on Forge. Pack availability checks now run in parallel instead of one-by-one, reducing wait times from 15 seconds to a few seconds.
• Grid and detail navigation. Switching between the tile grid and pack details in the Patreon Library is now instant instead of re-fetching all data on each click.
