v3.3.3

A first-run release: the setup step every new install begins with was
English-only, and the quick start did not say where to find the token it
asks for. Drop-in.

Fixed

• The setup-token step is translated. Its label, placeholder and hint
  were hardcoded English while everything around them was localised, so in
  36 of the 37 supported languages the very first screen a new install shows
  was untranslated. The token path is passed as a parameter, so translators
  control where it falls in the sentence.
• The Docker quick start now says where the setup token is. The command
  runs detached, so nothing is printed, and the onboarding wizard then asks
  for a token the reader has never seen. The README now shows both ways to
  retrieve it (docker logs muximux | grep token, or cat data/.setup-token).

Changed

• Container images report the same version metadata as the binaries. An
  image built from a tag previously reported v3.3.2 with the full 40-char
  commit while a binary from that same tag reported 3.3.2 with a short
  one; both now use the short form without the leading v, and the build
  date comes from build time rather than the commit timestamp.
