Yes - Running Ollama on my M2 Mac it times out.

Describe the solution you'd like
Either a longer timeout - 1000s or better a configurable timeout.

Describe alternatives you've considered
It appears to be set here

Additional context

I'm really enjoying using this. Thanks.

If you'd be receptive to a PR, I'd propose modifying genkit/go/plugins/ollama/ollama.go:

• adding Timeout int to type Config L148
• adding timeout int to var state struct L44
• add a look at Timeout and default to 30 if zero or set if not in Init L165
• actually use it in L204
