fix(ci): restore multi-OS validation with cargo check

Use cargo check on native platforms (Linux, macOS, Windows) instead of
cross-compilation. This is necessary because headless_chrome has native
dependencies that don't cross-compile.

Using cargo check instead of full builds provides:
- Platform validation for native dependencies
- Much faster than full builds (no codegen/linking)
- Excludes xtask which is development-only
