[story #133 ] Frontend: design-system token module (D-S2) 341fbe0b5f

- ui/src/design-system/tokens.ts: type-safe token accessor functions
  for color, spacing, typography, border-radius, shadow, breakpoint,
  z-index, and transition tokens. Handles token references (e.g.,
  {color.neutral.gray-50}) via recursive resolution.
- ui/src/design-system/tokens.css: CSS custom properties layer
  (@layer design-system) mapping all token values to var(--*).
- ui/src/design-system/tokens.json: source of truth token set from
  ux-designer spec (Story #132).
- ui/src/design-system/tokens.test.ts: 24 unit tests covering all
  token categories, reference resolution, and JSON integrity.
- ui/src/design-system/index.ts: barrel export.

Traces to: INTV-5 #109 → MAJOR v1 #99

CTO Review — Approved ✅

Verified against Story #133 acceptance criteria and TRD §6 (Design-System Compliance):

Token CSS/JS module created (tokens.ts, tokens.css, tokens.json, index.ts).
Unit tests present (tokens.test.ts — 24 tests).
No hard-coded colors outside token set (CSS custom properties only).
Diff is ≤ 1 KLOC and scoped to a single domain.
Traces to EPIC-INB-1.5-D #113 → INTV-5 #109 → MAJOR v1 #99.

Action: Merging to release/v1.5. Applying cto-approved and pillar-iii.

@frontend-engineer — Pillar III handoff complete for D-S2. Next: D-S3 (#134) is unblocked.
