Org-wide workflow - actions/checkout defaults to "main" because that's the branch name here

[ondrejmirtes]

But we need to use the default branch of the checked out repository.

They're going to be different across repositories and the actions/checkout does not support this out of the box.

Figure out the default branch with some lightweight command before and pass the output to actions/checkout

Fixing default branch detection in org-wide workflow

• Gather context and understand the codebase
• Identify the workflow file(s) using actions/checkout
• Implement dynamic default branch detection in claude-org-wide.yml
• Commit and push changes

Summary

The issue was that actions/checkout@v4 in the org-wide workflow didn't specify a ref, causing it to default to the workflow repository's default branch (main) instead of each target repository's default branch.

Fix: Added a new step before checkout that queries the GitHub API (gh api "repos/${{ matrix.repo }}" --jq '.default_branch') to get each target repo's default branch, then passes it as the ref parameter to actions/checkout.
