Support `--from` argument for uvx command run

[daltonnyx]

I have an agentic system that already implemented acp and want to integrate into registry named agentcrew.
However its execution command is different from package name agentcrew-ai itself (due to someone already take the agentcrew and I cannot contact to the owner to get the PyPI name). So the command need to run must pass the --from argument to run with uvx.

It would be nice if we can add the --from argument support for uvx run
or could I use something like this in agent.json:

"distribution": {
    "uvx": {
      "package": "--from=agentcrew-ai agentcrew",
      "args": [
        "acp"
      ]
    }
  }

Hermes Agent is blocked by the same package-vs-executable limitation.

Hermes ACP works via:

uvx --from 'hermes-agent[acp]==0.14.0' hermes-acp --check

but this is not equivalent to:

uvx 'hermes-agent[acp]==0.14.0' ...

The package is hermes-agent[acp], while the ACP entrypoint executable is hermes-acp (or hermes acp). Without an explicit command field, the registry cannot represent that launch shape and ends up relying on the package-name/default executable, which is not the ACP server.

So +1 on supporting the uvx --from <package> <cmd> <args...> shape. The same abstraction would also map cleanly to npm as npx --package <package> <cmd> <args...>.
