feat: implement nse-dev Python package with full test suite (27 tests)

Pure Python: cryptography lib for AES-256-GCM + secp256k1 for Schnorr
signing. Bech32 npub encoding. MemoryStorage + FileStorage backends.
Generate/sign/verify round-trips, kind 0 support, wrong-key rejection,
blob security. pyproject.toml ready for PyPI.
