🔥 Remove Vite scaffold leftovers

- Delete public/vite.svg, src/typescript.svg, src/style.css
- Empty public/ directory removed
- .npmignore: drop 'public/' entry (directory no longer exists), add
  .oxlintrc.json and .oxfmtrc.json to ignore list
- cspell: add .oxfmtrc, .oxlintrc, .sortpackagerc to dictionary so
  config-file name references aren't flagged
- lefthook: drop 'outdated' from pre-commit (kept in commands block for
  explicit CI invocation); it shouldn't block commits for being behind on
  upstream patch releases
