docs: regenerate HTML examples; skip benchmark tests without benchmarks/; py3.9 aarch64 install note (#427)

* docs: regenerate HTML examples for current default output

The committed samples predated the report-only duplicate default, the
outlier flag default and the not-assessed quality-debt dimensions (#420):
rows now read 205 -> 205, revenue shows outliers -> flag (7 flagged), and
the quality_debt total is 0.34 with schema_drift/category_churn unknown.

Regenerated with scripts/generate_html_examples.py. The action timeline's
duration and the quality-debt run_at timestamp are run-dependent and no
renderer option omits them, so those lines change on every regeneration.

* test: skip benchmark tests when benchmarks/ is absent

The sdist ships tests/ but not benchmarks/. conftest.py only filters
module-level imports, so tests that read benchmarks/ inside the test body
failed or errored from an unpacked sdist. The bench_streaming fixture now
uses pytest.importorskip (as the cleanbench suites do), and the entity
resolution smoke test and benchmark-stream CLI test skip when the
benchmark file is missing. The CLI test also runs from the repo root, since
the command resolves benchmarks/ against the working directory.

* docs: note Python 3.9 on Linux aarch64 builds the privacy stack from source

thinc 8.3.4 and blis 1.2.0 publish no cp39 Linux aarch64 wheel, and spacy
3.8.7 (the py3.9 cap) requires thinc>=8.3.4,<8.4, so no pin avoids the
source build. Document it in the install guide and next to the py3.9 caps
in pyproject.toml. Dependency pins are unchanged.
