Allow parallel tool calling

[hugoattal]

For now, the LLM execute tools one at a time. But sometimes, it needs to call multiple tools that can be executed in parallel. This would improve the token consumption and avoid back and forth requests.

Google describe this here: https://ai.google.dev/gemini-api/docs/function-calling?example=meeting#parallel_function_calling

Ollama describe this here: https://docs.ollama.com/capabilities/tool-calling#parallel-tool-calling

This seems to be supported on Vercel's AI SDK: https://ai-sdk.dev/cookbook/node/call-tools-in-parallel

Ooops, seems like it's already the case!

I'll have to find why it's not doing it in my case...

EDIT: Fixed, I just had to write it down in my system.md
