feat(spec)!: prune dead aria/performance from ReportSchema + dogfood the live report chart (report-liveness close-out) (#3496)

* feat(spec)!: prune dead aria/performance from ReportSchema + dogfood the live report chart (report-liveness close-out)

Follow-up to the #3463 report cleanup, closing out the 2026-06 ReportSchema
liveness audit. That audit flagged `aria` and `performance` as dead — declared
on ReportSchema (editable in the Studio report form) but read by no renderer.

- spec: removed ReportSchema.aria (AriaPropsSchema) + ReportSchema.performance
  (PerformanceConfigSchema) and the now-orphan imports. Both schemas stay
  exported (still used by views/pages/charts); ReportChart keeps its own aria
  from ChartConfigSchema. No manifest/export change; report.mdx regenerated.
  Ships minor per the launch-window breaking-as-minor policy.
- showcase: added `showcase_hours_by_status_chart` — a summary report with a
  `chart` block (est_hours by status, bar) + an Analytics nav item. This
  dogfoods the live DatasetReportChart path (chart.xAxis/yAxis over the bound
  dataset), which had no showcase coverage; browser-verified rendering.
- docs/audits: the 2026-06 report-liveness audit is refreshed with a resolution
  banner (chart = WIRED not dead, aria/performance pruned, re-exports removed,
  joined preview fixed), and the audits README section 2 annotates the resolved
  report slice while leaving the open chart-view/dashboard debt untouched.

* test(showcase): bump report-count assertion to 4 for the new chart report

seed.test.ts hardcoded 3 reports; the new showcase_hours_by_status_chart
makes it 4 (summary, chart, matrix, joined).

+feat(spec)!: prune the dead `aria` / `performance` props from ReportSchema (report-liveness close-out)
+
+Follow-up to the #3463 report cleanup. The 2026-06 ReportSchema liveness audit
+flagged `aria` and `performance` as dead — declared on `ReportSchema` (and
+editable in the Studio report form) but read by **no renderer**. This removes
+them. Every other finding from that audit is now closed too: `chart` turned out
+to be **live** (`DatasetReportRenderer` plots `chart.xAxis`/`yAxis` via
+`DatasetReportChart`), and the obsolete sub-schemas / naming-drift / joined-preview
+items were resolved by #3463 and earlier work.
+
+- Removed `ReportSchema.aria` (`AriaPropsSchema`) and `ReportSchema.performance`
+  (`PerformanceConfigSchema`), dropping the now-orphan imports. Both schemas
+  remain exported and are still used by other metadata types (views, pages,
+  charts) — only the report's use of them is removed. `ReportChart` keeps its
+  own `aria` (inherited from `ChartConfigSchema`).
+- No manifest key or public export changes (`aria`/`performance` were properties,
+  not schemas); `report.mdx` regenerated.
+
+**Migration**: nothing an author writes changes — no first-party or example
+report set `aria`/`performance`. Reports carry no ARIA/performance overrides;
+use the dataset/view surface for those concerns. Ships as `minor` per the
+launch-window breaking-as-minor policy.
