github: improvements for node drift wf (#12309)

* fix(workflow): improve Node.js version drift detection accuracy

1. Fix source URL regex: now captures 'Github: https://github.com/...'
   pattern (pipe-separated), not just '# Source: https://github.com/...'
   This was causing ~50 scripts to show 'No GitHub source'

2. Fix semver comparison: engines.node constraints like '>=18.0.0'
   no longer flag version 22 as drift. >= and ^ constraints are now
   properly evaluated (our_version >= min_major = satisfied)

3. Add fallback detection: when no Dockerfile or engines.node is found,
   check .nvmrc and .node-version files for Node version hints

4. Add subdirectory search: Dockerfile and package.json are now found
   via GitHub API tree search, not just in repo root

5. Use GitHub API to detect default branch instead of guessing
   main/master/dev with multiple HEAD requests

* fix typos in node_version

* runs on vps
