v1.0.1 — fixes the failing workflow in the v1.0.0 tarball

A fix release cut the same day as 1.0.0, because 1.0.0 shipped a workflow
that fails on checkout.

Fixed

If you took the v1.0.0 source tarball, its tests workflow fails
immediately. Cloning main was always fine; only the tagged snapshot is
affected. Nothing about the scraper itself is different — the parser, the
engines and the output are byte-identical between the two tags.

• .github/workflows/tests.yml carried its own inlined copies of two
  checks that also exist in .github/ci_checks.py. The sample-output copy
  still imported Player and Transfer, the row classes this repo replaced
  with a single Product before its first release, so the workflow failed on
  a schema that is correct. Both steps now call the shipped checker — which
  also widens the --help check from seven entry points to eight — and no
  python heredocs remain in that workflow.

Added

• The README now records the canary's first live run: a bare GitHub Actions
  runner, a freshly installed Playwright Chromium and no secret configured
  scraped /us/makeup/lips/ and reported 16 rows, 16 priced,
  status=complete, with every canary assertion passing. That is a third
  independent address behind the "the paid path is not required" claim,
  alongside a residential curl and the same connection through a real
  browser.
