Bytes a kPubkeySignature signed envelope adds to the unsigned transaction:
the one-entry signature vector (count, key ID, signature) and the present
pubkey_claim_key option holding the key.
Reserve this much when bounding an unsigned transaction against a
signed-transaction size limit: 116 bytes for Ed25519 and 5,284 bytes for
ML-DSA-65 (a 3,309-byte signature and a 1,952-byte key).
