feat: Gemma 3 Support

[yhg8423]

Feature Description

Currently, Google's Gemma 3 models are released. It would enhance its utility and expand compatibility for users seeking to integrate the latest models into their applications.

The Solution

The node-llama-cpp cannot load model architecture of Gemma 3 now. The information about Gemma 3 gguf should be added.

Considered Alternatives

It just added new model to library, so I think there is no other ways to alternate the solution.

Additional Context

I'll release a new version next week that will come with the latest llama.cpp release, which supports Gemma 3 models.

You can always build the latest llama.cpp release in node-llama-cpp to use the latest features, even before a new version of node-llama-cpp is released.

There's currently an issue with the latest release of llama.cpp, so you can use release b4880 for now, which includes support for Gemma 3, but doesn't have the issue from the latest release.
Run this command inside your project directory to download this release and build it:

npx --no node-llama-cpp source download --release b4880

Oh, I see! Thanks! 👍

Command looked promising! Not sure where to go from here:

@briancullinan2 Do you use the latest version of node-llama-cpp? (version 3.6.0)
If you do, please run this command inside your project and attach its result so I can help you:

npx --no node-llama-cpp inspect gpu

[briancullinan2]

I believe I'm using the latest version. Other models work fine, but that's the first time I've tried that npx compile command.

mmap: supported

Is there another version I could try other than --release b4880 that would narrow down if it is my machine/build process. I imagine the distributed pre-built binaries are working in my case since it didn't rebuild on install? Maybe it is a bug in the build process on Mac?
