Add instructions to get public key on windows

This focuses on Windows first, but coudl be used for Mac
and possibly linux in the future.

Some users are new to containers and unsure where the server logs go

The linux build now support parallel CPU builds to speed things up.
This also exposes AMD GPU targets as an optional setting for advaced
users who want to alter our default set.

A few obvious levels were adjusted, but generally everything mapped to "info" level.

After executing the `userdel ollama` command, I saw this message:

```sh
$ sudo userdel ollama
userdel: group ollama not removed because it has other members.
```

Which reminded me that I had to remove the dangling group too. For completeness, the uninstall instructions should do this too.

Thanks!

This reduces the built-in linux version to not use any vector extensions
which enables the resulting builds to run under Rosetta on MacOS in
Docker.  Then at runtime it checks for the actual CPU vector
extensions and loads the best CPU library available

Fixed assistant in the example response.
