  Install the opt-in bundled `claude` CLI, pinned to
  `ClaudeWrapper.Bundled.pinned_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.
