fix: switch reqwest TLS backend from rustls to native-tls

reqwest 0.13 defaults to rustls -> aws-lc-rs which requires cmake/nasm
in minimal build environments. Switch owlry-plugin-weather to native-tls
(system OpenSSL). Also add scripts/aur-local-test for clean chroot
testing and .gitignore for build artifact exclusion.
