Description

Tracking riscv64 wheel support for sentencepiece (no riscv64 wheels on PyPI for 0.2.2).

The native build trips abseil's subword-atomics static_assert under GCC 13, but RISE's cibuildwheel in manylinux_2_39_riscv64 (which ships GCC 14) builds it cleanly.

Build workflow: #165 (validated on native riscv64 hardware, 60 tests passing).

Research direction

Start with build workflow #165 and its manylinux_2_39_riscv64 configuration, then review how the sentencepiece 0.2.2 wheel is built. Done means the workflow produces a riscv64 wheel successfully, with the existing native-hardware validation and 60 passing tests preserved.
