v4.1.7 — refreshed README (quickstart/teardown install)
Docs only. Refreshed the README (the PyPI page was dated): the one-command attestor quickstart install + attestor teardown uninstall, current version stamps, corrected Install-for-Claude-Code section (namespaced /attestor:install-attestor, plugin enable step, real attestor-*-local container names), and CLI table. No code changes vs 4.1.6.
