fix(agent-team): review-round cap counts only reviewer verdicts (LOGIC-04)

_review_round_index counted EVERY review_verdicts entry, including the synthetic
human-gate verdict graph._apply_plan_decision folds in on a "request changes"
(reviewer == "human_plan_gate"). That inflated the count so a revised plan could
escalate prematurely without a fresh adversarial review.

Now counts only reviewer-authored verdicts: a new _is_reviewer_verdict excludes
entries tagged reviewer=="human_plan_gate" (read from the verdict dict's own
field — no graph.py import). A human request_changes now grants the revised plan
a fresh reviewer-round budget. Termination still bounded by MAX_PLAN_GATE_VISITS
(each request_changes consumes one gate visit). 1490 passed.
