v0.1.2

Added

• Shareable image. The --html card now has a Save as image button that
  renders a 1200×630 PNG in your browser and saves it locally. Nothing is
  uploaded — the image is drawn on a canvas and saved through an object URL, and
  only aggregate numbers ever reach the page.

Changed

• The HTML card is written to ~/.agent-wrapped/card.html instead of a
  system temp path. Everything the tool writes now lives in one directory you can
  find again. If you scripted the old temp path, update it; the stale file is
  harmless and your OS will clear it.

Fixed

• The "open it with" hint was macOS-only. Linux and Windows users were told to
  run open, which does not exist there. It now prints xdg-open or start as
  appropriate.
