- Regenerate `normalization_data.c.oss` using ICU 77.1 with `filters.json` enabled ("normalization": "include") rather than bundling the entire unfiltered ICU data archive. This reduces the source data file from ~91 MB to ~616 KB (and compiled in-binary `.rodata` from ~32 MB to ~220 KB across dependent shared libraries).
- Add shared library symbol stripping (`strip -x` on macOS, `strip --strip-unneeded` on Linux) in `build_pip_package.py` to eliminate unnecessary DWARF debug sections and local symbol tables from wheels.
- Drops the final `.whl` package size from ~60-95 MB down to ~5-7 MB, resolving PyPI upload limits.
