fix: install script pulls working model and creates hackcode-uncensored alias

The 8b model was removed from Ollama registry (404). Now the script:
- Auto-detects RAM and picks the best model that fits
- Tries multiple fallbacks if a model is unavailable
- Creates the hackcode-uncensored Ollama alias via Modelfile
- Works fully out of the box with just curl | bash
