chore: restrict npm package contents and add NOTICE

- add a files whitelist so only dist and the top-level docs are published;
  this drops tests, benchmark, docs, examples, docker-compose files, CI
  config and dot-directories such as .claude/.specify/.omc from the tarball
- add the ASF NOTICE file
- add repository/homepage/bugs metadata and set the author
- clean dist before building so deleted sources no longer leave stale
  artifacts behind in the package
