docs(adr-117): point README + user-guide at the live PyPI releases

Both packages are now live on PyPI; bring the in-repo docs up to
match. Keep both updates brief — the canonical surface
documentation lives on the PyPI project pages themselves.

Root README (Option 4 block):
- Switch the default `pip install` example to `ruview` (the brand
  name) and note `wifi-densepose` is equivalent.
- Add live PyPI version badges for both packages.

docs/user-guide.md (§Python wheel):
- Replace the single-install example with a table showing both
  PyPI projects and their import names so users see the choice
  immediately.
- Add three short usage snippets (vitals, live sensing-server WS,
  HA-MIND semantic-primitive MQTT listener) so the guide doubles
  as a "what does this thing do?" reference for someone landing
  via pip.
- Note the cibuildwheel matrix for multi-arch wheels.
- Add the `pytest tests/` + `pytest bench/` source-build verify
  steps.

No code or test changes.
