Security fixes and WCAG 2.1 AA accessibility for safe deployment

[Copilot]

Addresses security vulnerabilities and implements accessibility for Blind and Neurodivergent users to enable safe deployment.

Security

• Updated 1,752 packages via npm audit fix
• Fixed DoS vulnerabilities: Next.js (GHSA-5j59-xgg2-r9c4), ws (GHSA-3h5v-q93c-6h6q), glob (GHSA-5j98-mcp5-4vw2)
• CodeQL scan: 0 alerts
• 23 non-critical vulnerabilities remain in transitive/dev dependencies (documented in SECURITY.md)
• Confirmed React 18.x usage (not vulnerable to CVE-2025-55182)

Accessibility (WCAG 2.1 AA)

Enhanced components with multi-sensory feedback:

WalletConnect.tsx

// ARIA live regions announce connection status
<div role="region" aria-label="Wallet connection">
  <div aria-live="polite" aria-atomic="true">
    {isConnected ? `Wallet connected. Address: ${account.address}` : 'Wallet not connected'}
  </div>
  {/* Audio (540Hz tone) + haptic (double pulse) + voice synthesis on success */}
</div>

TransactionFeedback.tsx

// Progress announcements + reduced motion support
<div role="alert" aria-live="assertive" 
     aria-label={`${status}. ${type} transaction for ${amount} ${symbol}`}>
  <div role="progressbar" aria-valuenow={progress} 
       aria-label={`Transaction progress: ${progress}%`}>
  </div>
</div>

globals.css

• Focus indicators: 3px blue outline (WCAG AA)
• Color contrast: 13.84:1 body text (exceeds AAA)
• Touch targets: 44x44px minimum
• @media (prefers-reduced-motion) / @media (prefers-contrast) support
• .sr-only class and skip-to-content link

Documentation

Created 4 comprehensive guides (~45K characters):

• .github/copilot-instructions.md - Development standards, security practices, accessibility requirements
• ACCESSIBILITY_TESTING_GUIDE.md - Screen reader, keyboard, visual, haptic testing procedures
• ACCESSIBILITY_WORKFLOWS.md - Complete user flows with multi-sensory feedback matrix
• SECURITY_IMPLEMENTATION_SUMMARY.md - Vulnerability tracking and remediation status

Multi-Sensory Feedback

All state changes now provide:

• Visual: Color-coded states (green=success, red=error, orange=pending)
• Audio: Harmonic tones (432-540 Hz) + Web Speech API announcements
• Haptic: Vibration patterns (success: double pulse, error: triple pulse)
• Screen Reader: ARIA labels, live regions, semantic HTML

Target: 2+ billion users with accessibility needs.
