Provide macOS SDK for the apple cross-build (#26)

The first run of this branch failed: cargo-zigbuild can't cross-link the *-apple-darwin targets on the Linux runner because zig bundles glibc/musl but NOT Apple's non-redistributable libSystem/frameworks. std + iana-time-zone (via chrono) link CoreFoundation, so a macOS SDK is required (rustls only removed the Security framework, not the SDK dependency — the earlier "no SDK needed" claim was wrong). Fetch a pinned macOS SDK (joseluisq/macosx-sdks 12.3, immutable release asset) and point cargo-zigbuild at it via SDKROOT before the apple builds; set MACOSX_DEPLOYMENT_TARGET=11.0 for a Big Sur floor. Also add the macos binaries to the CI artifacts list. Closes #26 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
