Fix CI failures: ROBIN dependency management and Python wheel builds

Major fixes:
- Fixed ROBIN FetchContent configuration using FetchContent_MakeAvailable()
- Set USE_SYSTEM_ROBIN=OFF across all workflows for consistent bundled builds
- Simplified Python wheel environment variables and build dependencies
- Removed lint workflow as requested (too subtle)
- Updated pyproject.toml with proper scikit-build-core configuration

Changes:
- robin.cmake: Use GIT_REPOSITORY with FetchContent_MakeAvailable()
- ci-cpp.yml: Set ROBIN to OFF for all platforms
- ci-python.yml: Simplified cibuildwheel configuration, removed system deps
- ci-ros2.yml: Updated ROBIN setting for consistency
- pyproject.toml: Added cmake.source-dir and build args

This should resolve the build failures and enable `pip install kiss_matcher`
