ollama.create should not use process unless necessary to support client side use

[willcallender]

Every other function in this library works in React, and is much more convenient than manually writing a function to handle the CURL API. However trying to run ollama.create in React gives an error due to process being unavailable. This might be neccessary when paths are provided, but when their not process.cwd doesn't need to be called at all. Tthis worked fine for me.

interface OllamaCreateParams {
  model: string;
  modelfile: string;
}

export async function ollama_create({ model, modelfile }: OllamaCreateParams) {
  try {
    const response = await fetch('http://localhost:11434/api/create', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({ 'model': model, 'modelfile': modelfile, 'stream': false }),
    });
    
    if (!response.ok) {
      throw new Error('Failed to create model');
    }

    return response.status;

  } catch (error) {
    console.error('Error creating model:', error);
    throw error;
  }
}
