* fix(#3315): surface compression-exhausted/no-final-answer turns as errors (#3316)
When Hermes Agent exhausts context compression in a long tool-heavy turn, the
streamed result can end on a tool result / assistant(tool_calls) turn with no
final assistant answer. WebUI was finalizing that as a completed response.
Now _session_lacks_final_assistant_answer() + _agent_result_terminal_failure()
classify these as terminal failures and surface an apperror instead. The
compression session-id migration + pre-compression snapshot now run BEFORE the
terminal-failure return (ordering bug from the prior hold) so state stays
consistent when exhaustion fires after the agent rotated session_id.
