server: do not attempt to parse offset file as gguf

This logic was causing issues for me when importing a gguf that had some padding at the end of the file. The valid gguf would be read, but then it would try to read the offset as a different gguf file. This does not seem right.

convert: quantize from safetensors needs kv (#10675)
When creating a quantized model from safetensors we
need the array KV values to be loaded.Changing this
value to -1 loads the KV values on the returned
layer to be used and saved during quantization.

Move quantization to new backend (#10363)
* Move quantization logic to GGML via new backend

This moves the model aware logic to Go code and calls GGMLs quantization code for model creation.

* Remove "add model quantizations"

This is no longer needed now that quantization is implemented in Go+GGML code directly.

there's no cross-device copy

server: validate local path on safetensor create (#9379)
More validation during the safetensor creation process.
Properly handle relative paths (like ./model.safetensors) while rejecting absolute paths
Add comprehensive test coverage for various paths
No functionality changes for valid inputs - existing workflows remain unaffected
Leverages Go 1.24's new os.Root functionality for secure containment

feat: add new Ollama engine using ggml through cgo

This change introduces a new way to run pretrained models. It introduces 3 high level interfaces and a bunch of smaller helper interfaces to facilitate this.

- `model.Model` defines the interface for a model architecture. Models such as `llama` and `mllama`, which are provided as examples, can implement the model's forward propagation in the `Forward` method. This method will be called to generate completions. This interface can be found in `model/model.go`
- `ml.Backend` defines the interface for a backend tensor library, in this case `ggml`. Among other things, a Backend is responsible for loading a pretrained model into hardware (GPU, CPU, etc) and providing an interface for Models to access loaded tensors. This interface can be found in `ml/backend.go`
- `ml.Tensor` defines the interface for a tensor and tensor operations

This is the first implementation of the new engine. Follow up PRs will implement more features:

- non-greedy sampling (#8410)
- integration with Ollama and KV caching (#8301)
- more model support (#9080) with more coming soon

Update the /api/create endpoint to use JSON (#7935)
Replaces `POST /api/create` to use JSON instead of a Modelfile.

This is a breaking change.
