fix: CV split-button height + LinkedIn redirect; tooling tidy

- CV split button: make the chevron <details> flex and the summary full-height so the
  toggle matches the primary button height (verified 39.1px == 39.1px)
- nginx: /Linkedin now 301s to the real profile (linkedin.com/in/connor-babbington)
- prettier-ignore .pnpm-store; gitignore .claude/settings.local.json; e2e port 4321->4399;
  dev preview autoPort
