  Install the opt-in bundled `claude` CLI (current stable, verified `>=`
  `ClaudeWrapper.Bundled.minimum_version/0`) into the package's `priv/bin/`.

      mix claude_wrapper.install

  No-op when an up-to-date binary is already installed. Reinstalls on a
  version mismatch. This downloads from the network; the default PATH-based
  resolution does not need it.
