Download Ollama

Set up Ollama so I can build with open models.

Ollama runs open models in two ways:
- Locally, on this computer. Speed depends on the hardware. Large models are slow on a computer without a strong GPU.
- In Ollama's cloud. Cloud models run on Ollama's servers, so they are fast on any computer and need no download. In the CLI, a cloud model name ends in :cloud, for example gemma4:cloud. From code, apps call the API at https://ollama.com.

Before you do anything, learn Ollama from its docs:
- Read the docs index at https://docs.ollama.com/llms.txt.
- Read https://docs.ollama.com/quickstart.md, https://docs.ollama.com/cloud.md, and https://docs.ollama.com/gpu.md.
- If I want to call Ollama from code, read https://docs.ollama.com/api/introduction.md. If this project already uses the OpenAI or Anthropic SDK, also read https://docs.ollama.com/api/openai-compatibility.md or https://docs.ollama.com/api/anthropic-compatibility.md.
- For any other question, search the full docs at https://docs.ollama.com/llms-full.txt.

Then:
1. If the ollama command is not installed, install the Ollama CLI. On macOS or Linux, run: curl -fsSL https://ollama.com/install.sh | sh. On Windows, run in PowerShell: irm https://ollama.com/install.ps1 | iex.
2. Check this computer's GPU and memory against https://docs.ollama.com/gpu.md.
3. Ask me what I want to build.
4. Recommend local models, cloud models, or both for that, and tell me why. If local models would be slow on this computer, recommend cloud models. Cloud models need usage credits or a paid plan.

Do not sign in, create an API key, or use an API key for me. If I choose cloud models, tell me to run ollama signin, or to create a key at https://ollama.com/settings/keys.
