0.18.0 - Shorter Color Tags

• --short-hex forces every text-mode color tag into the three-digit
  <color="FFF"> form by quantizing each channel to the nearest of 16 levels.
  Tags drop from 16 characters to 13, and neighbouring pixels that quantize to
  the same color merge into one run, so it saves space twice over, at the
  cost of some color fidelity. Available for both image and video text modes,
  on the CLI and in both GUI panels.
• The Monaspace Argon preset now defaults to --width-scale 2.05 rather than
  2, closing the seam between glyph cells.
