 * Seed for the default (deterministic) deployer keypair.

 * The deployer keypair is derived as
 * `Keypair.fromRawEd25519Seed(sha256(utf8(DEFAULT_DEPLOYER_SEED)))`. Deriving it
 * from a fixed, well-known string makes smart-wallet contract IDs reproducible
 * across clients from a passkey credential ID alone (`salt = sha256(keyId)`,
 * `deployer = this keypair`), which is exactly what the indexer reverse-lookup
 * (keyId → contract) depends on.
 *
 * This value MUST remain `"kalepail"`: every wallet ever deployed by passkey-kit
 * used this deployer, and the derivation is load-bearing for discovery. The
 * deployer only pays fees and salts the deploy — it never controls the wallet —
 * but it IS a shared, publicly-derivable keypair. Provide your own
 * `deploySource` secret for a dedicated fee payer (note: a different deployer
 * changes the derived contract addresses and breaks keyId → contract discovery).
