feat: initial EcoArk HarmonyOS wheel pipeline skeleton

- wheel_pipeline.py: CLI entry point for repack/rebuild flow
- pipeline/detect.py: detect pure vs native extension wheels
- pipeline/repack.py: repack pure-Python wheels with harmonyos_arm64 tag
- pipeline/rebuild.py: native wheel rebuild entry (stub for OHOS NDK)
- pipeline/cli.py: argument parsing and orchestration
- Makefile: convenience targets (repack, rebuild, clean)
- README.md: documentation with usage and limitations
- examples/gen_test_wheels.py: test wheel generator
- output/: output directory for generated wheels

examples/gen_test_wheels.py
