FR-5a: a new, standalone four-stage Org meta-graph (renderOrgMetaGraph and
friends) rather than extending the existing 3-node renderOrgGraphTopology
(left untouched, it's pinned by test_graph_console_smoke.js). Each stage
expands in place: planner/coder/validator reuse renderGraphVisualizerPanel
unmodified against that stage's latest run (identified via org_nodes_involved,
Phase 2c's replacement for the removed single-value org_node column);
planner_reviewer has no self-planned work_graph_run, so it shows its
planner_review_verdict execution_event history instead (new
task_query.py::_planner_review_events_for_task(), mirroring the existing
_loop_back_events_for_run() pattern).
FR-5b: an attempt_number-ordered, click-to-reveal feedback timeline built
from loop_back_events, which was already being fetched but never rendered.
New frontend/test_org_meta_graph_smoke.js (35 assertions, same vm.Context
sandbox convention as the existing 4 smoke tests).
