fix(review-suite): detect nested finding-verifier faults; harden render/fault markers

code-reviewer verdict.py: finding-verifier now completes "successfully"
with fault markers INSIDE its FINDING_VERIFIER_RESULTS payload
(parse_fault's `pipeline-fault` sentinel id, verify_fault / verdict_gate
crash-guard notes prefixed PIPELINE-FAULT:), which the old
"Agent node failed:" prefix check never saw — a dead parse degraded
silently to "unverified" with no fault recorded. Detect them, anchored on
the sentinel id / note prefix only (never a substring over the report),
counted over the raw entry list so duplicate crash-guard ids are not
collapsed. Faults lead the attention list uncapped; the display cap of 5
applies to non-fault entries; the "always-human trigger(s) fired" reason
fires only when non-fault triggers exist.

code-reviewer render.py: CONTRACT comments at the verdict and summary
lines review-gauntlet's gate parses; every LLM-influenced value rendered
after the summary line (dropped_titles, rigor, bar_provenance,
resolved_surfaces, reason) is newline-sanitised so none can forge a
second summary line.

finding-verifier verdict_gate.py: the outer crash-guard note carries the
PIPELINE-FAULT: prefix (the after-retry UNVERIFIABLE path stays
unprefixed — model misbehaviour, not infrastructure); README names all
three emitters.

deep-research: vet_fault's UNVETTED note tells the critic not to request
revision solely because the assessment is unavailable (it matched
critique's PREPRINT/UNVERIFIED REVISE trigger verbatim, burning the
revision budget on an infra fault); vet_fault and critique_fault dedupe
repeated faults and preserve accumulated faults on crash via
safe_faults(); question_fault keeps its plan-pinned prefix and appends the
lane's question identity so distinct dead lanes no longer collapse in
combine_findings' dedupe.
