Subject: [PATCH] CI hygiene: bump deprecated action versions, ignore local
 Claude settings

- actions/checkout@v3 -> v4 and actions/cache@v3 -> v4 (v3 majors are
  EOL and depend on the deprecated Node 16 runtime)
- buildindex action: node16 -> node20 (GitHub is deprecating Node 16
  actions; index.js has no Node-16-specific API usage)
- .gitignore: add .claude/ so local Claude Code tool settings never
  get committed to this shared repo

Left the committed node_modules/ under .github/actions/buildindex/ alone
for now -- replacing it with an ncc-bundled dist/ is a bigger, separate
change and this PR is meant to be low-risk.
