v0.1.3

Added

• Screenshots in the docs: the guide and every bundled plugin's page open
  on a screenshot of the IDE, drawn from Porta itself each time the site is
  built, so they always show the current version.

Fixed

• The cursor no longer jumps past a popup's shadow: typing with the
  completion popup open, its shadow cast along the caret's row put the
  terminal cursor at the shadow's far end instead of after what you typed.
• The numeric keypad types its digits and operators under the Kitty keyboard
  protocol, where they used to be read as keys with no name and typed nothing.
