Subject: [PATCH 01/13] chdb: prefer a newer chdb-core GitHub release over the
 PyPI package

chdb-core cannot cut PyPI releases frequently, but every GitHub release
(including release candidates) publishes the full wheel set as assets.
After the regular pip install, compare the installed version with the
newest chdb-core release tag (PEP 440 ordering over the full release
list, so rc tags participate and an rc of an already-released version
can never win): if the release is strictly newer, install its wheel for
the current architecture instead. If the check fails, e.g. offline, the
PyPI build stays. The effective version is printed either way.
