Note

Introduce HD Taproot (BIP86) wallet with p2tr derivation, PSBT/taproot signing, watch‑only/descriptors, import/export, and UI creation flow.

• Wallets/Core:
  • Add HDTaprootWallet (BIP86 m/86'/0'/0', p2tr) with taproot address derivation, PSBT inputs, taproot signing, and Silent Payments p2tr support.
  • Extend abstractions for p2tr (segwitType), cache master fingerprint, and p2tr coinselect weight.
  • Include HDTaprootWallet in serialization/deserialization and exported types.
• Import/Discovery:
  • Merge Electrum formats with BlueWallet formats adding p2tr; map p2tr to HDTaprootWallet during BIP39 scanning.
  • Support output descriptors parsing (tr(...)) and add WalletDescriptor helper; generate descriptors for taproot watch‑only exports.
• Watch‑only:
  • Initialize HD watch‑only as Taproot when xpub + BIP86 path; support descriptor imports; expose p2tr PSBT fields.
• UI:
  • Add Taproot option to Add Wallet screen; update custom derivation import to include HDTaprootWallet.
  • Show/export taproot watch‑only as descriptor in Wallet Export and XPUB screens.
• Transactions/PSBT:
  • Add taproot derivations to PSBT outputs/inputs (tapBip32Derivation, tapInternalKey) and sign via signTaprootInput.
  • Message signing options clarified to exclude p2tr.
• Tests:
  • New unit/integration tests for HD Taproot, descriptor handling, and import flow; adjust counts for offline import.
• Misc:
  • Add android:restart npm script; bump iOS pods (lottie-react-native, RNLocalize).
