Chromium 154 breaks KDE Plasma via fontconfig cache bug

Chromium 154 creates broken fontconfig cache symlinks in ~/.cache/fontconfig, crashing plasmashell, the panel, lock screen and Qt apps on KDE Plasma. A patch has been released; users should update their browser and system and clear the fontconfig cache if needed.

• The bug affects all Chromium 154 browsers, including Chrome, Brave and Opera
• Symptoms include plasmashell crashes, a vanishing panel and lock screen failures
• A fix has been pushed; updating the browser and system resolves it
• Clearing ~/.cache/fontconfig is recommended if issues persist
