/**
 * @module utils/serialization
 * @description JSON-safe serialization helpers for on-chain account data.
 *
 * On-chain Anchor account objects contain `PublicKey` and `BN` instances
 * that are not JSON-serializable. These helpers convert them to plain
 * strings (`base58` and decimal `string`) recursively.
 *
 * @category Utils
 * @since v0.1.0
 *
 * @example
 * ```ts
 * import { serializeAccount } from "@synapse-sap/sdk/utils";
 *
 * const raw = await program.account.agent.fetch(pda);
 * const json = serializeAccount(raw);
 * // { authority: "GBL...", totalCalls: "42", ... }
 * ```
