- Parse reasoning_summary_text (and related) SSE events in OpenAI Responses
streaming; forward deltas to on_token and return reasoning_content on
LLMResponse so thinking-mode rows get event_payload in the store.
- When emitting chat/final from turn_runner, include event_type/event_payload
and merge reasoning_content from earlier assistant rows in the same
turn_uuid so the collapsed reasoning fold matches what streamed.

- Add runtime/plan_agent_v2 package and shims; gateway/direct_loop/WS wiring
- Admin chat: interaction mode and specialist only in user menu; session API stores memory_mode and execution_mode only
- POST /admin/api/chat/user-mode mirrors plan_agent_version to AIA_EXPERT_PLAN_AGENT_V2_ENABLED (v2 to 1, v1 to 0)
- Composer cleanup (hidden mode select, no reasoning toggle in meta bar); tests and _local/system.env.example
