 * Load (once) and return the vendored WASM module.

 * The glue is imported via this package's own `./wasm` subpath export so one line
 * serves every target: `require`/Jest get the CJS glue, Node `import` the full ESM
 * glue, and bundlers/browsers a Node-free ESM glue (`mpt_crypto.web.mjs`). All three
 * wrap the same `.wasm`; both ESM glues use `new URL(import.meta.url)` so bundlers
 * emit it as an asset. See the `package.json` exports and `src/wasm.d.ts`.
 *
 * A transient load failure is retried automatically; if every attempt still
 * fails the rejection is not cached, so a later call retries afresh rather than
 * returning the same permanent rejection.
 *
 * Provenance: `mpt_crypto.{js,mjs,wasm}` come from mpt-crypto's
 * `.github/scripts/build-wasm.sh` and are vendored by `scripts/fetch-wasm.sh`.
