+ * Register every single-shot EVM client scheme on a client.
+ *
+ * - `exact`        — direct ERC-3009 / Permit2 transfer.
+ * - `upto`         — variable-amount (metered) payment up to a cap.
+ * - `auth-capture` — escrow-backed authorize/capture used by x402r
+ *   refundable endpoints; signs ERC-3009 (default) or Permit2
+ *   (`assetTransferMethod: "permit2"`).
+ *
+ * All three are stateless and take the same `ClientEvmSigner`, so one signer
+ * wires up every path. Registering a scheme an endpoint doesn't use is
+ * harmless — the client matches on the `scheme` of each `accepts` entry.
+ *
+ * `batch-settlement` is intentionally omitted: it is stateful (per-channel
+ * deposits, vouchers, on-chain channel recovery) and needs persistent client
+ * channel storage. The wallet builds a fresh per-request `x402Client`, so the
+ * scheme's default in-memory storage would silently lose channel state
+ * between requests. Wiring it up correctly is separate work.
