Client APIs

Clients talk to the Dex server (not directly to Temporal for Flow operations).

Common RPCs (see docs/design/idl-renames.md):

• StartFlow — start a Flow run
• InvokeRPC — call a Flow RPC
• PublishToChannel — publish messages
• GetAttributes / SetAttributes
• WaitForFlow / WaitForStepCompletion / WaitForAttribute
• SearchFlows, ResetFlow, StopFlow, SkipTimer, TriggerContinueAsNew

SDKs wrap these with typed helpers.
