build: configured docker build pipelines for cargo native addons

- Switched Docker images to build native addons via cargo/napi-rs (`OMP_NATIVE_BUILD_BACKEND=cargo`) instead of Bazel.
- Updated Cargo.toml workspace members explicitly to prevent loading errors from stale directories under crates/.
- Added depth-agnostic patterns to .dockerignore files to exclude nested build outputs from Docker build contexts.
- Added OMP_NATIVE_CARGO_PROFILE environment variable to support configuring cargo profiles for addon builds.
