handle_verdict(rejected): the reason is now pulled from the issue latest Plane
comment (_latest_comment_reason: GET comments, newest by created_at, HTML
stripped) instead of a fixed stub. Slava writes the reason in a comment before
flipping the status to Rejected. Falls back to a fixed note when there is no
comment / the API call fails.
tests: add test_status_only_verdict.py (test_inreview_comment_does_not_revert
[bug 3 root], test_any_comment_no_pipeline_action,
test_approved_status_advances_without_inprogress_reset,
test_rejected_status_pulls_reason_from_comment) and
test_inprogress_from_needs_input_relaunches_analyst in test_status_trigger.py.
Rewrote the comment-based tests (test_verdict_status, test_plane_approved/
rejected in test_webhooks) under the status-only model: comments are no-ops,
verdicts come from status changes.
Feature 2. The issue updated dispatch (shipped with the status-trigger handler)
also routes Approved -> _try_advance_stage (== :approved: comment) and Rejected ->
_rollback_stage (== :rejected: comment). The :rejected: comment branch was
refactored into the shared _rollback_stage so both mechanisms behave identically;
a status reject passes Reason: (rejected via status, see latest comment) since no
inline reason arrives with a status change. Comments stay fully working. This
commit adds test_verdict_status.py proving both status and comment paths funnel
into the same advance/rollback logic.
