0.9.0

Changes

• feat(keys): bind cmd+left/right to line start and end

This release is a point in main's history, not a build to install. It carries
no download: a dmg is large and you can build one in about forty seconds with
npm run install-app, which installs it as Taco Shells Dev, beside the
stable app rather than over it.

The current stable version is whichever release GitHub marks as Latest.
