Pin GitHub Actions to commit SHAs for security (#386)

Replace mutable tag references with immutable commit SHAs in
codeql-analysis.yml and check-dist.yml to prevent supply chain attacks.

Actions pinned:
- actions/checkout@v6.0.2
- github/codeql-action/init@v4
- github/codeql-action/autobuild@v4
- github/codeql-action/analyze@v4
- actions/setup-node@v6.3.0
- actions/upload-artifact@v7.0.0
