This Core resumes reconstructed waits on wakes met during replay, stops stale waits from forcing an output task, and keeps a retained task with caching off. It also vendors the stream record envelope, which plain gen-protos now writes.

This PR pins the external-streams Core that carries the external stream repairs.
What changed?
temporalio/bridge/sdk-corepoints at the repaired Core, and.gitmodulesnames its branch.poe gen-protosaddstemporalio/api/stream/v1withStreamRecordandStreamRecordKind. The pin forces it, and nothing reads it until the interface mirror PR.### Fixedchangelog lines for the Core fixes this pin brings.Part of AI-198 (epic AI-37).
Why?
The Core fixes live entirely in Rust, so Python gets them by moving the pin. With caching off, Core now keeps a retained external-stream task until its boundary. Wakes met during replay resume the waits they belong to. A stale wait no longer forces an output replacement task. The record envelope comes with the same Core, because the external Core vendors it right under these fixes. The old branch layered the api diff with
scripts/gen_stream_api_protos.py. That isn't needed here, since plainpoe gen-protosreads what Core vendors.How did you test it?
Link to a test plan if any -
The bridge builds and
poe lintis clean. The Nexus system generator runs on this pin and gives back the committed output. The external stream suite, the worker workflow, visitor and client suites pass on the dev server. The channel cases pass with-Eagainst a channel server.
