/**
 * Generic RPC proxy over a Web Worker. Post `{ id, method, args }` messages
 * and resolve the matching promise when `{ id, result }` or `{ id, error }`
 * comes back. Works with any worker that follows this message protocol.
 *
 * Pass a pre-constructed Worker so that bundlers (webpack/turbopack) can
 * statically detect the `new Worker(new URL(...))` pattern at the call site.
