v0.1.1

Fixed

• No compiler warning on Elixir 1.20. The host routing re-checked the
  literal kinds Mutare.AST.literal_value/1 already guarantees, which 1.20's
  type inference reports as a test that always succeeds while compiling the
  dependency (and which failed the package's own warnings-as-errors CI). The
  redundant check is gone; behaviour is unchanged.
• The README's install snippet names real versions (~> 0.1 for both
  mutare and mutare_ecto) instead of the "~> ..." placeholders left
  from before publication.
