/**
 * Measure a transaction's resource use by simulating it at the maximum limits.
 * `build` receives the limits and must return serialized (signature slots may be
 * zero) v1 bytes. Throws when simulation fails or the RPC omits loaded-data size,
 * rather than returning a zero that v1 would treat as "no budget".
 *
 * The result is valid only for the instruction set `build` compiles (e.g. SOL
 * and SPL shields differ). `rpcUrl` is called with a plain `fetch` and only a
 * `content-type` header — an RPC that authenticates via custom headers must be
 * reached another way, with the resulting limits passed explicitly.
