Allow stdin and multiple prompt args

[ericcurtin]

So we can do things like this:

$ cat main.go | ./model-cli run ai/smollm2 Explain this file:

other tools allow this.

@p1-0tr @xenoscopic @ilopezluna PTAL. Could someone click the build button for me please to check this passes?

I like the stdin support, I'm not sure where I land on the multi-arg concatenation, but I guess it does allow more "natural" usage maybe, I just worry it might constrain future CLI changes where we want to use positional arguments for something else. Maybe @mia-docker can comment.

I'm taking influence from RamaLama and Ollama, both allows unlimited prompt args

Suggested changes complete and repushed

Need approval for a build again

@p1-0tr @xenoscopic anything we can do to move this along?

[p1-0tr]

I'd be happy to merge this, but I'll let @xenoscopic have the last word.
