* docs: use HTTPS for the astyle and cppcheck links in README
Both links were still `http://`. `astyle.sourceforge.net` serves HTTPS
directly; `cppcheck.sourceforge.net` redirects to
`https://cppcheck.sourceforge.io`, which is also the URL already used in
`docs/mkdocs/docs/community/quality_assurance.md`, so the redirect is
skipped here.

* CI: suppress -Wc2y-extensions for Clang
Clang 22.1 (now shipped by silkeh/clang:latest) diagnoses __COUNTER__ as a
C2y extension, and does so in C++ mode as well. Under -Weverything -Werror
this breaks every ci_test_clang_cxx* / ci_test_clang_libcxx_cxx* target,
independently of the code under test.
The library itself does not use __COUNTER__; all diagnostics originate in
vendored Doctest (DOCTEST_ANONYMOUS, used by TEST_CASE and SECTION).
