Changes

My Space could briefly show an empty folder before its first listing arrived. Fast requests could also flash a skeleton.
Panel entrance motion could briefly expose a vertical scrollbar.

• Track initial directory loading and delay skeleton visibility.
• Retain a visible skeleton briefly to avoid flicker.
• Delay the module loading placeholder for fast code-split navigation.
• Hide vertical overflow during panel entrance, then restore scrolling after animation or a timeout.
