Add GitHub Actions workflow that runs a smoke test with ASAN-enabled Ruby to detect memory errors (buffer overflows, use-after-free, leaks) in the C extension layer. - Use ruby/setup-ruby with `ruby-version: asan` - LD_PRELOAD libstdc++ to work around __cxa_throw ASAN CHECK failures when non-ASAN DuckDB throws C++ exceptions internally - Test step uses continue-on-error until all ASAN issues are fixed - Cache DuckDB builds with ASAN-specific key to avoid collisions This workflow is a starting point. The plan is to incrementally fix ASAN-detected issues and eventually run the full test suite under ASAN.
