Closes #29

• Preserve valid UTF-8 character boundaries in clean_code_for_fuzzy (packages/redup-fast-hash/src/simhash.rs) so native SimHash matches the Python reference implementation on Unicode source text without panics.
• Add embedded Rust regression vectors and a Python conformance test (tests/test_tokens_hasher_rust.py) that builds the candidate Rust binary and verifies parity across Unicode vectors.
