v0.2.1 — dashboard visuals + deploy pipeline

Piece 1 — Visuals
- Add KPI bento bar (score tile with run-health pill, cost tile, last-run tile).
  Run-health pill shows 'All models healthy' / 'N model(s) degraded' / 'No run
  yet' sourced from PRV_Model_Registry health fields via collector.
- Add config-change trendline marker: inline configMarker Chart.js plugin draws
  a vertical dashed orange line + pin at every config_version boundary.
  Legend swatch + annotation note appear when breaks exist.
- Chart sits in fixed .prv-chartbox (300px); typeof-Chart guard + .prv-noscript
  fallback — cannot grow layout, degrades gracefully offline.
- PRV_Dashboard_Renderer: new class owns bento tile + trendline rendering.
  PRV_Ai_Visibility_Panel is now a thin orchestrator (237 lines).
- PRV_Ai_Visibility_Collector: trendline query now includes MIN(config_version)
  per run; collect() adds last_run_counts and config_versions to payload.
- PRV_Admin_Page: get_dashboard_css() returns Assay dark palette CSS.

Piece 2 — Deploy pipeline
- .github/workflows/deploy.yml: on push to main, runs CI, rsyncs plugin to
  Hostinger PROD (excl. .git .github tests phpunit composer vendor phpcs *.md),
  purges LiteSpeed, health-checks (200/403). Standalone — not smoke-gated.

DoD
- Version 0.2.1 in header + constant; CHANGELOG, ARCHITECTURE, CONVENTIONS,
  CONTEXT all updated same commit.
- tests/unit/test-dashboard-panel.php: 27 assertions.
- Pre-push checks: no PHP built-in name shadows in bootstrap.php; all
  includes/*.php files <= 300 lines (max: 298).
