Example with model via `include_bytes!`?

Re: the use-case I mentioned in #2177 where you can use include_bytes! and SliceSafetensors to ship a model directly embedded in the output binary.

Would it be useful to have an example of that in candle-examples or in the candle book? If so I can add one.

Review the use case in issue #2177 and inspect the existing candle-examples and Candle book structures. Determine whether an example using include_bytes! with SliceSafetensors belongs in either location; done means adding a focused example or documenting the approach, with its placement and scope agreed.
