Keep conversation turns distinct and history stable (#7990)

* fix(app): keep autonomous turns distinct and readable

Hidden system prompts merged autonomous work into the previous response and reopened completed turns. Preserve canonical turn boundaries and expose their triggers, while making received messages attributable and expanded turn details readable in one step.

* fix(timeline): mount history at actual run boundaries

* fix(timeline): load and retain complete available turns

* fix(app): summarize actions and preserve conversation events

* test(timeline): verify whole-turn paging stays responsive

* fix(app): group reasoning according to thinking preference

* test(app): align history journeys with whole-turn loading
