/**
 * Submit a signed Soroban transaction and poll until confirmed.
 *
 * @param signedXdr - Base64-encoded XDR of the signed transaction
 * @param network - Stellar network name
 * @param sorobanRpcUrl - Optional override Soroban RPC endpoint (e.g. a keyed
 *   Alchemy URL); becomes the primary with the SDK's public endpoints kept as
 *   failover. Omit to use the public endpoints.
 * @returns The transaction hash once the network confirms it as successful
 * @throws {@link AugustTimeoutError} when the transaction is not confirmed
 *   within the poll budget (`MAX_POLL_ATTEMPTS`).
 * @throws {@link AugustSDKError} when the RPC rejects the submission or the
 *   transaction confirms as failed. Its `context` carries `{ network, status }`
 *   plus, when the result XDR decodes, a `resultCode` string holding the
 *   transaction-level reason (e.g. `"txBadSeq"`, `"txTooLate"`); `resultCode`
 *   is `undefined` when the code cannot be decoded.
 *
 * Side effect: a transaction whose `resultCode` is `txFailed` — the operation
 * itself ran and failed — and whose envelope shows a vault `redeem` is relayed
 * to that vault's curator (fire-and-forget, deduped — see
 * {@link reportRedeemFailure}). Nothing else alerts: an RPC-rejected
 * broadcast is a retryable race, a poll timeout is indeterminate (the
 * transaction may yet succeed), and any other result code means the redeem
 * never executed.
 * @example
 * ```ts
 * try {
 *   const hash = await submitStellarTransaction(signedXdr, 'mainnet');
 * } catch (err) {
 *   if (err instanceof AugustSDKError && err.context?.resultCode === 'txBadSeq') {
 *     // stale sequence number — rebuild the transaction and resubmit
 *   }
 * }
 * ```
