v0.2.0

• Diagrams inside a blockquote can now be edited. The payload is rewritten with
  the quote prefix the fence already had — > , > > , > and indented
  variants are all reproduced verbatim — and editing a quotation asks for
  confirmation first. A fence whose payload line is not itself quoted, or one
  broken by a blank line, is still refused: rewriting either would change the
  document's structure rather than just its payload.
• Every diagram gains a View full size action, available to readers who
  cannot edit it — including anonymous visitors on a public task link. It shows
  the same image as large as the screen allows, with no frame and no network
  request; clicking the picture toggles between fitting the viewport and the
  diagram's own size, and Escape, the close button or the backdrop closes it.
• Diagrams stay legible on Kanboard's dark theme. A diagram whose own background
  is transparent used to be dark strokes on #222; every diagram now renders on
  a constant light surface, in every theme, so it looks the same wherever it is
  read. The plugin's own placeholder and error colours follow Kanboard's theme
  variables instead of being fixed to the light theme's values, and the editor
  backdrop matches the page rather than flashing white.
