saravanakumardb1 57a09c31dd feat(ai-ui): @bytelyst/ai-ui@0.5.0 — Wave 13.C trust surfaces (CostMeter / ConfidenceTag / RefusalCard) 
Three new primitives — every product chat / agent surface should
adopt these to make the model honest about what it is doing.

──────────────────────────────────────────────────────────────────
<CostMeter>  ·  Wave 13.C.1
──────────────────────────────────────────────────────────────────
  packages/ai-ui/src/CostMeter.tsx (new)

  - Live token + (optional) USD readout
  - 4 tiers: neutral (no budget) · ok (<70 %) · warn (>=70 %) ·
    danger (>=95 %) — token-tinted via color-mix() so all four
    palettes degrade gracefully on browsers without var() support
  - NaN-safe — non-finite / negative inputs floor to 0
  - role=status + aria-live=polite + aria-label assembles a
    screen-reader-friendly sentence
  - Mini-bar visual indicator at the end of the pill when budget
    is provided
  - Pure passive surface — never warns / prompts / blocks

──────────────────────────────────────────────────────────────────
<ConfidenceTag>  ·  Wave 13.C.2
──────────────────────────────────────────────────────────────────
  packages/ai-ui/src/ConfidenceTag.tsx (new)

  - Accepts `number | 'high' | 'medium' | 'low' | 'unknown'`
  - Default thresholds 0.8 / 0.5 — both overridable
  - Out-of-range numerics map to `unknown` (no false confidence)
  - Optional `showScore` renders a tabular-nums percent suffix
  - 4 token-tinted palettes (success / warning / danger /
    neutral) — pair naturally with <CitationChip> for the full
    'show your work' story

──────────────────────────────────────────────────────────────────
<RefusalCard>  ·  Wave 13.C.3
──────────────────────────────────────────────────────────────────
  packages/ai-ui/src/RefusalCard.tsx (new)

  - 6 reason archetypes — safety / policy / capability /
    authorization / rate-limit / unknown — each with a typed
    heading + glyph
  - Calm warning palette (never red) — refusals are not errors
  - Up to 3 actionable next steps (further entries silently
    clipped) — one is markable `primary` to render as filled CTA
  - Optional `footer` slot for policy doc links
  - role=note + composite aria-label covering heading +
    explanation
