Fix push protection hook blocking pushes when codeant CLI is unavailable

The fallback branch in the cliPath hook used && which caused non-zero
exit when neither the bundled CLI nor global codeant was found, blocking
pushes even though no scan ran. Changed to || exit 0 to match the
non-cliPath branch behavior.
