ci: ran the mnemopi suite in the workspace bucket

The stated reason for the exclusion no longer holds: no test in
packages/mnemopi loads the fastembed model. The suites that touch embeddings
inject a deterministic in-process provider via setEmbeddingProviderForTests,
and the model-cache suite mocks globalThis.fetch, so nothing downloads or
reads a ~270MB model. On a clean checkout with no model cached, all 448 tests
across 73 files pass on linux-x64 in 11.7s.

packages/mnemopi moves into fastWorkspacePackages, which the workspace bucket
runs and which local-ts already covered through localOnlyWorkspacePackages, so
the local full run is unchanged.
