Fix the Lite bento layout, unframe screenshots, stack notifications

[fylorn]

• Menu bar tile: text on the left, the menu rising from the tile's bottom edge on the right; the large empty area is gone.
• Bottom row: keys, dry run and notifications share one picture height, so the three headings line up.
• Notifications tile: a macOS-style notification stack (newest in front, older ones peeking out below, the next one sliding in from above) using the titles and bodies the app actually sends for a blocked tool call, a used-up subscription quota and a lost remote connection.
• Screenshots: the Lite story screen and the home page's Lite shot no longer get a second frame; the screenshots already include the macOS window and its shadow. A soft glow sits behind them instead.
• Core hero: the Chinese title breaks after 「适用于桌面与服务器的」, so it no longer runs under the terminal at 1024–1680 px.

Checked at 1440, 1100, 900 and 390 px in both languages: no horizontal scroll, headings aligned, title clear of the terminal. Reduced motion shows the stack at rest.
