## Message

```
refactor(orchestration): split thread-not-sendable into typed errors

Effect service conventions: ThreadManagementThreadNotSendableError
carried an Archived/NoSteerableRun reason union and switched on
reason._tag inside the message getter. Modelled as two error classes
(ThreadManagementThreadArchivedError, ThreadManagementNoSteerableRunError);
both still map to the MCP thread_not_sendable failure code.
