Least Privilege

How secrets: inherit over-privilege happens in GitHub Actions reusable workflows and how to fix it

A high-severity security finding was identified in `templates/claude-workflow/workflows/claude.yml` where `secrets: inherit` passed every repository secret to a reusable workflow, violating the principle of least privilege. The fix explicitly passes only `CLAUDE_CODE_OAUTH_TOKEN`—the single secret the called workflow actually needs—drastically reducing the blast radius if the reusable workflow is ever compromised.
