matevip 1affbd7b82 feat(agent): loop-engineering robustness — goal continuation, plan re-plan, stall detection ... - goal: continue (not skip) on max-iterations and evidence-insufficient turns. A max-iterations turn grants a fresh iteration budget ("hard continuation"), bounded per run and sized into the graph recursion ceiling, so a task too big for one budget keeps going instead of stalling until the next user message. - plan-execute: re-plan the remaining work on a step exception, and on a signature-based stall (repeated failures / identical results / no usable result) instead of advancing dependent steps with junk; bounded by a per-run re-plan cap, with a graduated change-strategy nudge before the hard stop. - plan-execute: auto-derive a goal from a genuine multi-step plan, seeding the acceptance criteria from the plan steps, so the goal subsystem engages without the model calling setGoal; broadcast goal_created so the UI hydrates. - react: refund the iteration for setup-only rounds (load_skill / enable_tool) so a tight budget is not eaten by the load-then-use two-step. - ui: re-fetch the active goal when a turn finishes so a goal created or mutated mid-conversation surfaces without depending on an SSE event. - streaming: make retry backoff / total-time budget instance fields with a test-only seam; clarify that the wall-clock budget (not max-retries) bounds a sustained SERVER_ERROR loop to ~8 attempts, fixing the slow/flaky retry test.		2026-06-17 06:37:08 +08:00
