📄 Description

The second argument to bufio.Scanner's Buffer() is the maximum size that will ever be allocated (set to 512 KB), silently dropping larger responses from Ollama.

When sending large requests to /api/generate (MB-range), MB-sized contexts are returned and the whole response is silently dropped, causing users to complain.

This change keeps the default buffer size at 512 KB, but raises the maximum buffer size to 5 MB.

This fixes https://github.com/ollama/ollama/issues/11811 - or at least bumps the size by a factor of ten.
