[Feature Request]: Add a config option to disable Co-authored-by in Git commits

Problem statement

Currently, every time I commit changes using Mistral Vibe, it automatically adds itself as a co-author in the Git commit message (via the Co-authored-by:). While I understand the intent, I’d like to disable this behavior deterministically.

• Even if I explicitly state in my AGENTS.md that Mistral Vibe should not be added as a co-author, it still sometimes adds itself.
• There is no configuration option to control this behavior, unlike in Claude Code (which has an includeCoAuthoredBy setting).

Proposed solution

Add a configuration option (e.g., in config.toml) to disable the Co-authored-by globally. For example:

[git]
include_co_authored_by = false

Additional context

No response

[jacobsandersen]

it already exists -- include_commit_signature in config. set it to false and it will stop doing that

You're right. Thank you! 🙏
