Git Repo Normalize

When to use

Use this skill only when at least one trigger is present.
- The user explicitly asks to fix .gitattributes, line endings, or LF/CRLF warnings.
- Git emits LF will be replaced by CRLF, CRLF will be replaced by LF, or similar warnings.
- The repository has no committed root .gitattributes EOL policy and the current task needs one.
- A repo-wide diff or staging state suggests line-ending churn and you need to normalize intentionally.
Do not use this skill just because the task touches Git.
- Routine commits, version bumps, tags, changelog edits, CI workflow edits, and diff review do not trigger normalization by themselves.
- If the repo already has a committed EOL policy and no line-ending problem is in scope, continue the main task without renormalizing.
