Decoding flow (outline)

• Aggregate QR frames into a UR object (e.g., using @ngraveio/bc-ur's URDecoder).

• Inspect ur.type === 'crypto-hdkey' and parse CryptoHDKey from CBOR bytes using the registry helper.

• Extract fields such as name, note, chainCode, bip32 xpub, origin/children paths, and source fingerprint (xfp).
