fix: Bidirectional hover sync + theme-aware CV text colors

**Bug 1: Bidirectional Hover Sync**
- Fixed hover sync to work in BOTH directions
- Hovering left buttons → highlights menu buttons (was working)
- Hovering menu buttons → highlights left buttons (NOW WORKING)
- Added .download-btn and .print-friendly-btn to syncPdfHover/syncPrintHover selectors

**Bug 2: Theme-Aware CV Text Colors**
- CV content text now adapts to light/dark themes
- Light theme: Dark text (#1a1a1a, #333333) for readability
- Dark theme: Light text (#e0e0e0, #d0d0d0) for readability
- Added theme-specific overrides for --text-dark and --text-gray variables
- Solution uses CSS variables (not hardcoded) for future flexibility

Changes:
- static/hyperscript/hover-sync._hs: Added left-side button selectors
- static/css/color-theme.css: Added legacy variable overrides for all themes
