libghostty v0.0.11

Added

• Color utilities: parseColor, parsePaletteEntry,
  parseX11ColorName, x11ColorNames, palette generation, and luminance
  helpers expose Ghostty's runtime color behavior.
• Unicode width utilities: unicodeCodepointWidth and
  unicodeGraphemeWidth expose Ghostty's terminal cell-width rules.
• Color-scheme reports: ColorScheme.encode() encodes terminal
  color-scheme reporting responses.
• Kitty graphics cache stamps: KittyGraphics.generation and
  KittyImage.generation let renderers detect placement and image cache
  invalidation without comparing image bytes.
• Absolute viewport scrolling: Terminal.scrollToRow() restores viewport
  positions using the same row space as Scrollbar.offset.

Changed

• Kitty graphics pixel data: stored image payloads are exposed as decoded,
  decompressed pixels, including PNG and zlib-compressed transmissions.
• Scrollbar metadata: scrollbar reads use Ghostty's cached offset and
  incrementally maintained total, reducing repeated scrollback traversal.
