redactGitHubTokens covers ghp_, gho_, ghs_, ghr_, and github_pat_ tokens but misses ghu_ (GitHub App user-to-server tokens), one of the documented GitHub token prefixes. A ghu_ token appearing in issue or PR content passed through sanitization unredacted. Add the ghu_ pattern, mirroring the existing 40-character token patterns, with unit tests including the git-credential URL form.
