What
prefetchAllMcpResources resolves even if the per-client count comes up short.
Details
- Previously it only resolved once the per-client counter reached the expected total.
- It now also resolves when the underlying enumeration promise settles, so a short count cannot leave the prefetch pending forever.
Evidence
prefetchAllMcpResources
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
