Dark-Alex-17 0ce2654173 feat(TASK-023): deep-research hardening — fail-safe scripts, fault fallbacks, pipeline notes
R3 guards: parse_request (crash → ask_topic), bootstrap_research,
combine_findings (crash → fault-text findings; also lifts branch-local
PIPELINE-FAULT findings into pipeline_faults, deduped), reflexion_gate
(crash fails forward to synthesize), incorporate_feedback (crash still
loops with a generic feedback note), verify_sources (top-level guard +
pipeline_notes fold).

Fallbacks per the plan's naming pins: plan → plan_fault → end_fault
(fail-closed; gains state_updates plan_failure per the TASK-016 rule);
research_one_question → branch-local question_fault (map collects the
fault finding); vet_sources/critique → degrade-visibly markers that
continue to the stage each node's own next pointed to; synthesize →
synth_fault → end_fault. end_fault renders
'DEEP_RESEARCH FAILED — PIPELINE-FAULT: <fault text>'.

Accepted-path visibility: verify_sources folds pipeline_faults into
pipeline_notes ('' when fault-free), appended to end_accepted's output
and the approval question — happy-path output stays byte-identical.
initial_state seeds questions: [] so a dying plan inside the static
fan-out leaves the sibling knowledge_lookup lane mapping over zero
items while end_fault renders.

R5: 19 python3-guarded regression tests + GraphParser wiring test;
bundled warning baseline unchanged.

"""Entry router for deep-research.
Reads the caller's prompt from state. If it contains a usable research
topic, stores it as `topic` and falls through to the static `next`
(plan). If the prompt is empty, routes to `ask_topic` so the user can
supply one interactively.
Routing (`_next`):
- prompt present -> (no _next; static next: plan)
- prompt empty -> ask_topic
Fail-safe (R3): a crash here (e.g. malformed GRAPH_STATE) means the
caller's prompt cannot be read at all, so proceeding silently is
meaningless — the degraded route is `ask_topic`, which asks the user for
the topic directly, plus a PIPELINE-FAULT entry so the loss is visible in
the final report's Pipeline notes. Clobbering `pipeline_faults` is safe
here: this is the start node, so the list can only hold its initial [].
