README: amane run works now; tools: anim counts 20-500 ms gaps

- README install: the desktop's amane CLI saves ~/.cache/amane/amane-shell,
  so amane compile + amane run is the way to start the shell
- amane-remote.sh anim: with one window per monitor, gaps of 500 ms and
  more are other islands resting, not stutter
