Fix release workflow: anchor grep patterns to avoid AC_INIT line matches

The version extraction grep patterns were matching both the define()
lines AND the AC_INIT line, producing multi-line values that broke
GITHUB_OUTPUT. Fix by anchoring with ^define( and filtering with
grep -v ALPHA for core version lines.
