chore: trim root, move examples, drop committed uv.lock

- delete CONTRIB.md (superseded by CONTRIBUTING.md)
- delete requirements.txt (duplicated [project].dependencies)
- delete test_quick.py (ad-hoc smoke covered by tests/test_shims.py)
- rewrite example.py as examples/basic.py using the public API
  (from pyvyos import VyDevice) and drop the RuntimeWarning suppression
- move vagrant/ to examples/vagrant/
- stop tracking uv.lock and add it to .gitignore (library, not app)
- README: link the examples/ directory
- CHANGELOG: document the moves and removals
