Claude Code now appends a link to a Claude session in every commit

Claude code now appends every commit with this line, everyone is opted in automatically.

This link is only accessible to the user so it doesn't make sense to be put in a commit.

Claude-Session: https://claude.ai/code/session_...

There is a new setting that allows you to disable it.

    "sessionUrl": false
