docs: Update Input/Select/Card to semantic aliases + raise maturity to 83%

- RFC-002 Input:
  - Token Dependencies updated to semantic aliases with primitives
  - All tokens now map through color.surface, color.border, color.text, color.status
  - No direct color references (e.g., semantic-red-500 → color.status.danger)
  - Helper/error text uses semantic tokens

- RFC-003 Select:
  - Token Dependencies updated to semantic aliases with primitives
  - Dropdown, option, and error states use semantic tokens
  - Selected option uses color.action.primary at 10% opacity
  - No direct color references

- RFC-004 Card:
  - Token Dependencies updated to semantic aliases with primitives
  - Surface, border, text hierarchy use semantic tokens
  - Shadow tokens mapped to elevation system
  - No direct color references

- COMPLIANCE_MATRIX.md:
  - Input: 33% → 83%
  - Select: 33% → 83%
  - Card: 33% → 83%
  - All now have Governance ✅, Tokens ✅, Motion ✅, Accessibility ✅, AI ✅

Rationale: Semantic model first. Components never reference primitives.
Token contracts (purpose, allowed, forbidden) ensure correct usage.
Dark mode implementable via token swap without component changes.
