            BitCal is a header-only C++23 bit manipulation library. This release publishes the canonical source bundle only:

            - `bitcal-${{ github.ref_name }}.zip`
            - `bitcal-${{ github.ref_name }}.tar.gz`

            **BitCal 4.x contract:** bit_block, bit_view/const_bit_view, and free algorithms. x86-64 is the primary optimization and validation target.

            Included contents:

            - `include/bitcal/`
            - `cmake/`
            - `CMakeLists.txt`
            - License, README, and changelog files

            Validation follows retained CI and docs verification paths. No platform-specific binary archives are produced.
