Add Python test script that validates the TypeScript MuSig2 implementation against the BIP-327 reference implementation. The tests use JSON fixtures generated from the TypeScript test suite to ensure both implementations produce identical results at every step of the MuSig2 protocol. Validation includes key aggregation, taproot tweaking, deterministic nonce generation, partial signing, signature verification, and aggregation. Tests use fixed session IDs to ensure bit-for-bit identical outputs between both implementations. Issue: BTC-2652 Co-authored-by: llm-git <[email protected]>
