Merge remote-tracking branch 'origin/main' into pr-1466

design-tokens.test.ts:
  - STATUS_CONFIG: all 7 statuses have dot/label/bar
  - statusDotClass: known status returns dot, unknown/empty → bg-zinc-500
  - TIER_CONFIG: tiers 1-4 have label/color/border, T4 uses warm
  - COMM_TYPE_LABELS: a2a_send→sent, a2a_receive→received, task_update

palette-context.test.tsx:
  - normalizeStatus: online/degraded→emerald, failed→red, paused/not_configured→amber, unknown→zinc
  - tierCode: maps 1-4 to T1-T4
  - getPalette: null→base, identity guard, custom accent overrides, no mutation of MOL_LIGHT/MOL_DARK

theme-provider.test.tsx:
  - applyResolvedTheme: sets data-theme on html element
  - ThemeProvider: is a function (React component)
  - THEME_COOKIE = 'mol_theme', themeBootScript is a non-empty string
