ManuNotes 0.6.0

Added

• Per-card export in the deck: right-click a card (either layout) for
  a Markdown/Plain Text/Sticky Archive submenu that exports just that
  note, named after its title — matching the per-note export already on
  iOS.
• Scroll hint tile. When there are more notes than fit on screen, a
  dashed tile with a down-chevron appears above the "+" tile to signal
  that the card area actually scrolls.
• About window. A fixed "ManuNotes" label below the "+" tile (outside
  the scrolling area) opens a small About window with the app icon,
  name, developer credit, and version/build.

Fixed

• Cmd+C/Cmd+X/Cmd+V/Cmd+A now work in the note editor. This is an
  accessory app with no visible menu bar, so AppKit never installed the
  standard Edit menu that routes those key equivalents to the focused
  text view — a hidden Edit menu is now installed at launch to register
  them.
