52 install scripts had a project website in '# Source:' but no GitHub
link. Merged the GitHub repo URL into the Source header as:
# Source: https://website.com/ | Github: https://github.com/OWNER/REPO
Repos sourced from fetch_and_deploy_gh_release calls, get_latest_github_release
calls, or known project repos for npm/pip installed apps.
Two scripts (fumadocs, pve-scripts-local) had no Source line at all —
added one. Shinobi skipped (GitLab-only, no GitHub repo).
