v0.0.3

Changed

• The macOS installer now installs the fl command too: it links fl and flashlink in
  ~/.local/bin to the standalone binary the Finder menu uses, so Terminal and Finder run the same
  version and nothing depends on Node. It never overwrites an fl installed some other way, says
  when ~/.local/bin is not on your PATH (with the line to add), and when another fl comes first.
  Already installed? Run the install command again.
• The installer's output is clearer: grouped steps, colors on a terminal (not with NO_COLOR), and a
  "Next steps" list that only includes connecting to your Worker when that is still needed.
