Improved documentation¶

Fixed incorrect decorator usage in the under_cached_property() example code – by @meanmail.

Made Cython line tracing opt-in via the with-cython-tracing build config setting – by @bdraco.

Previously, line tracing was enabled by default in pyproject.toml, which caused build issues for some users and made wheels nearly twice as slow.

Now line tracing is only enabled when explicitly requested via pip install . --config-setting=with-cython-tracing=true or by setting the PROPCACHE_CYTHON_TRACING environment variable.
