This Core resumes parked external waits from channel notifications and keeps the server's subscriptions in step with the channels lang reports, so the bridge protos gain the WorkflowStreamChannels command.

This PR pins the external-streams Core that wakes parked stream readers through notification channels.
What changed?
temporalio/bridge/sdk-corepoints at the channel-wake Core, and.gitmodulesnames its branch.poe gen-protosadds theWorkflowStreamChannelsworkflow command to the bridge protos. That's the only generated change, and the pin forces it.Part of AI-198 (epic AI-37).
Why?
The next PR makes the external runtime report which channels its open readers listen on. Core needs this version to take that report and keep the server's subscriptions in step with it. It's also the Core that resumes a parked external wait when a channel notification arrives. Keeping the pin separate means the wake PR shows only Python.
How did you test it?
Link to a test plan if any -
The bridge builds and
poe lintis clean. The external stream suite, the worker workflow suite and the visitor tests pass on the dev server. The channel cases pass with-Eagainst a channel server. Nothing emits the new command yet.
