[WIP] Upstream sync checklist

[ARR4N]

• Run rename workflow from main with commit hash of version to update to
• Confirm version tag in workflow and note name of created branch
• Create new local branch off main
• On new branch: git merge origin/auto-rename-module_... (branch name from workflow)
• Files we're completely overwriting:git checkout --ours -- .github/workflows/go.yml .golangci.yml [...] and git add [same files]
• git status | grep "deleted by them" | awk '{print $NF}' | xargs git rm

The resulting change to main MUST include a merge commit that descends from the upstream code being brought in; it MUST NOT squash the upstream code. This will (a) result in a recent merge base for future sync merges that avoids having to re-resolve conflicts; and (b) integrate properly with cherry-picking for releases.
