-- Make the Python wheel build/install robust against platform tag mismatches.
-- pip wheel derives the platform tag from sysconfig.get_platform(), which can
-- differ from what SCons reconstructs (for example, host/jail OSVERSION
-- differences in Poudriere). Instead of hardcoding the expected wheel filename,
-- build a sentinel file and discover the actual .whl when installing.
-- See https://github.com/Cantera/cantera/issues/1862
