/**
 * Dogecoin & Litecoin P2PKH Adapter
 *
 * Builds P2PKH (Pay-to-Public-Key-Hash) transactions for Dogecoin and
 * Litecoin, attaches secp256k1 ECDSA signatures from the FROST threshold
 * signing network, and broadcasts via public APIs.
 *
 * These chains do NOT support Taproot/P2TR, so we use legacy P2PKH format
 * with ECDSA signatures (not Schnorr).
 *
 * No external dependencies — TX serialization implemented from scratch.
