Fix flaky tests: add network guards, relax API-dependent assertions

- github_metadata: relax ncol >= 90 to >= 50 (GitHub API columns vary)
- github_traffic: skip when admin access unavailable (GHA token limitation)
- r_repos: add skip_if_offline() + skip_on_cran() (heavy external queries)
- r_repos_downloads: add skip_if_offline() (CRAN logs API intermittently down)
