fix: improve navigation link contrast for WCAG AA compliance (#67)

## Summary

Fixes issue #61 - Active navigation link contrast was failing WCAG AA
requirements with only 1.72:1 contrast ratio. This PR updates the active
link color to achieve 3:1+ contrast for WCAG AA compliance.

## Changes

### CSS Updates (`src/styles/globals.css`)
- **Before**: `--active-light: rgb(34 211 238 / 1)` (cyan-400, #22d3ee)
- **After**: `--active-light: rgb(0 150 175 / 1)` (darker cyan)
- **Result**: Achieves 3:1+ contrast ratio on light background
- Dark mode color unchanged (already WCAG AA compliant)

### ROADMAP Updates
- Marked issue #61 as completed (Nov 16, 2025)
- Updated Executive Summary to reflect completion
- Updated Current Sprint progress
- Updated Issue Status Summary (12 open issues, down from 13)
- Updated Critical Path to show #61 completed
- Updated Effort Distribution (removed #61 from Small category)
- Updated Issues by Category (moved #61 to closed)
- Added comprehensive Changelog entry for Nov 16, 2025

## Testing

✅ **Unit Tests**: All 131 tests passing
✅ **Build**: Production build successful
✅ **Contrast Ratio**: Verified 3:1+ contrast on light background
✅ **Dark Mode**: Unchanged, already compliant

## Impact

### Accessibility
- ✅ Achieves WCAG AA compliance (3:1 minimum contrast)
- ✅ Improves usability for users with visual impairments
- ✅ Eliminates legal/compliance risk

### Affected Areas
- Home navigation link (when active)
- Code navigation link (when active)
- Contact navigation link (when active)
- All viewports: Mobile, Tablet, Desktop

## Implementation Approach

Chose **Option 1** from issue #61: "Darken the Cyan Color"
- Simplest solution
- Maintains design aesthetic
- Minimal code changes
- No breaking changes to component structure

## Screenshots

### Before (1.72:1 contrast - FAILS WCAG AA)
- Active link color: `rgb(34, 211, 238)` (cyan-400)
- Background: `rgb(250, 249, 246)` (off-white)
- Contrast ratio: 1.72:1 ❌

### After (3:1+ contrast - PASSES WCAG AA)
- Active link color: `rgb(0, 150, 175)` (darker cyan)
- Background: `rgb(250, 249, 246)` (off-white)
- Contrast ratio: 3:1+ ✅

## Next Steps

As documented in ROADMAP.md:
- 🟡 **#62** - Increase Touch Target Sizes for Mobile Accessibility
(NEXT)
- 🟡 **#63** - Fix Cumulative Layout Shift (CLS) on Mobile

## Closes

Closes #61
