Note

Upgrade bip32 to v5 and migrate Buffer-based wallet APIs/tests to Uint8Array, with supporting ECC and utility updates.

• Dependencies:
  • Upgrade bip32 from 3.x to 5.0.0 (lockfile updated; new sub-deps added).
• Core changes (Buffer → Uint8Array):
  • Wallet APIs now return/accept Uint8Array (e.g., _getNodePubkeyByIndex, _getPubkeyByAddress).
  • Replace Buffer hex conversions with helpers like uint8ArrayToHex; update getIdentityPubkey to return hex from Uint8Array.
  • Multisig: replace Buffer.compare with compareUint8Arrays in sortBuffers.
• ECC Integration:
  • Update TinySecp256k1Interface import for bip32 compatibility in noble_ecc.
• Tests:
  • Adjust expectations to use Uint8Array and uint8ArrayToHex; update PSBT derivation pubkey assertions accordingly.
