Add BIP-352 receiving crypto (scan, tweak, keys, address)
silentpay.js gains the receiving half of silent payments, validated against all
official BIP-352 vectors (29/29 receiving sub-cases):
- inputPubKey(): recover the eligible input pubkey from P2PKH/P2WPKH/P2SH-P2WPKH/
P2TR inputs (skips uncompressed keys, excludes NUMS script-path, hash160-matches
malleated P2PKH scriptSigs)
- silentPaymentTweak(): the oracle tweak input_hash*A (sum over eligible inputs,
input hash over all outpoints, point-at-infinity guarded) — used by the indexer
- silentPaymentScan(): ecdh = scan_priv*tweak, derive P_k = B_spend + t_k*G, match
the tx's taproot outputs, return per-output spend tweaks
- silentPaymentOutputPrivKey(), deriveSilentPaymentKeys() (m/352' paths),
encodeSilentPaymentAddress()
Labels not yet implemented (wallet uses a single no-label address).
