developer f6e81afe5e Harden agent guardrails and fix audited bugs
Gate hardening:
- strict + noUncheckedIndexedAccess in tsconfig.app.json; fix resulting errors
- check-tokens.mjs: scan inline style={{ }} in ts/tsx, ban named colors and
  rgb()/hsl()/oklch()/lab(), read multi-line values, fail on undefined var(--x)
- vitest (24 tests: overlay, icon-registry, useTimeout, token guard) wired into
  npm run check; GitHub Actions CI workflow

Single-source refactors:
- new Overlay primitive owns focus trap/Escape/scroll-lock/focus-restore and
  conditional aria-labelledby/aria-describedby; Dialog + Sheet are thin skins
  (overlayBehavior.ts exports trapTabKey/useOverlayLifecycle for SearchPalette)
- icon-registry.ts is the one icon map: strict IconName, aliases typed, dev
  throws on unknown names instead of silently rendering <Layers/>; IconMatrix
  consumes the shared registry (41 curated)
- useTimeout hook replaces fire-and-forget setTimeout in DeploymentModal,
  SettingsPanel, IconMatrix, CodeSample (timers die on close/unmount)

Bug fixes:
- SearchPalette: role=dialog/aria-modal, focus trap + restore, combobox/listbox
  semantics, labelled input, selection clamped to results
- theme: pre-paint script in index.html (localStorage -> prefers-color-scheme ->
  dark), useTheme no longer writes DOM during state init
- StatCard: direction (arrow) decoupled from trend (sentiment); latency drop
  renders green "↓ -4.2ms" instead of "↑ -4.2ms"
- sidebar collapse button wired (aria-pressed + collapsed rail CSS); pattern
  routing keys on patternId from library.ts, not English labels
- remove 25 dead legacy tokens (--panel*, --line*, --text-soft, --critical,
  --pink, --blue, ...); migrate --bg/--text/--positive/--warning usages
- title "Northstar Design System", real README, AGENTS.md structure/theme/
  overlay/registry/test docs updated; dev error sink (#dev-errors +
  ErrorBoundary) so agents can read runtime errors via inspect
