Developer 65bae95e3c feat(prometheus-direct-charting): slice 2 — gauge + mean widgets 
Add gauge widget (recharts RadialBarChart with configurable threshold
bands, scalar-only per SC-111) and mean widget (client-side average over
range-query window, scalar-only per SC-114). Extract shared _instant_query
helper from the metric path; _fetch_gauge and _fetch_mean dispatch in
PrometheusWidgetSource.fetch(). Both new widget kinds declared in
integrations/prometheus.py and frontend registry.

Backend: 305 pytest pass, ruff clean. Frontend: 136 vitest pass, build+lint green.

Developer 5dad98231f feat(prometheus-direct-charting): slice 1 — prom range query + chart rebrand 
Add PrometheusWidgetSource._fetch_chart hitting /api/v1/query_range directly
(SC-101..104). New shared helpers in widgets/prometheus_range.py:
step_for_window (window preset -> step, ~200pts) and normalize_prometheus_matrix
(extracted label/dedup rule, retargeted at Prom matrix, robust to malformed
data). Chart widget kind moved grafana->prometheus in both registries;
GrafanaChartWidget renamed -> PrometheusChartWidget (git mv, recharts body
preserved). Grafana binding/service untouched (removed in slice 3).

Backend: 298 pytest pass, ruff clean. Frontend: 128 vitest pass, build+lint green.

Developer d906b0392b spec(prometheus-direct-charting): add tasks (3 slices, each <=400 lines) 
S1 adds Prom chart (range query + rebrand, no grafana removal); S2 adds
gauge+mean; S3 removes grafana + config rewrite + changelog. Each slice
leaves pytest/npm build/npm lint green. Review-workload forecast per slice.

Developer 9b7415080b spec(prometheus-direct-charting): patch SC-116/118 for service-tabs refactor 
ObservabilityPage.tsx was refactored into service-tabs/; update removal
criteria to name real targets and whitelist the Dashboard.test fixture
shortcut-label collision.

Developer 78e273efe8 spec(prometheus-direct-charting): add design 
5 locked design decisions: step derivation formula (max(15, round(s/200))),
shared normalize_prometheus_matrix helper in widgets/prometheus_range.py,
recharts RadialBarChart gauge w/ threshold bands, mean via client-side
avg over query_range, 3-slice plan each <=400 lines.
Source-verified: ObservabilityPage refactored into service-tabs/ (map stale).

Developer b7e5ca3cbc spec(prometheus-direct-charting): add proposal + spec 
Drop Grafana as chart middleman; query Prometheus directly via
/api/v1/query_range. Rebrand GrafanaChartWidget -> PrometheusChartWidget,
add gauge + mean widget kinds, remove Grafana surface, rewrite stale
thin-dashboard rule in config.yaml. 27 acceptance requirements (SC-101..127).
