runway v0.1.1

Changed

• runway describe colors its diagram and explanation in terminals and CI
  logs: the service stands out, permissions are yellow and what they apply
  to cyan, names and values are cyan instead of quoted, lines and boxes are
  dimmed. Without colors (files, pipes, NO_COLOR, --color never) and in
  JSON, the output is unchanged: plain Markdown and ASCII.

Added

• Documentation: setting up shell completions for every shell, including
  fish when it does not come from Homebrew, and previewing
  describe --format mermaid from the terminal with mermaid-cli and a
  terminal image viewer.
