feat(ui): Add color-coordinated syntax, fix clipping, redesign flag browser

Major UI improvements addressing user feedback:

1. Color-Coordinated Syntax Highlighting
   - Command names: Bright cyan + bold
   - [OPTIONS]/[OPTION]: Yellow
   - UPPERCASE args (FILE, PATH, STRING): Magenta
   - Lowercase optional args: Green
   - Ellipsis (...): Dim white
   - Applied to both interactive menu and explain mode

2. Fixed Clipping Bug in Interactive Menu
   - Recalculated width allocations more conservatively
   - Changed to percentage-based DESC_WIDTH (40% of terminal)
   - Added min/max caps for widths
   - Improved spacing calculation (TERM_WIDTH - VISIBLE_WIDTH - 8)
   - Added safety bounds (min 3, max 20 spaces)
   - Syntax now always visible (truncated with ... if needed)

3. Redesigned Flag Browser for Better UX
   - Eliminated wasted dead space above fzf
   - Integrated syntax and description INTO fzf header
   - Created elegant box header with command info:
     - Command name
     - Colorized syntax
     - Description
   - Height increased to 95% for more flags visible
   - Preview window reduced to down:3:wrap
   - Removed echo spam ("Extracting flags...", "Found X flags...")
   - Clean, immediate transition to flag browser

4. Updated Function Signatures
   - show_flags() now accepts: cmd_name, syntax, description
   - browse_flags_fuzzy() now accepts: cmd_name, syntax, description
   - Interactive mode passes all three parameters
   - Explain mode uses colorize_syntax() function

5. New Functions
   - colorize_syntax(): Parse and colorize syntax by element type
   - Applied consistently across all display modes

User Experience Improvements:
- ✅ No more clipping - syntax always visible
- ✅ Instant recognition of parameter types via color
- ✅ No wasted screen space before flag browser
- ✅ Command info integrated cleanly in fzf interface
- ✅ Professional, color-coordinated appearance

Technical Details:
- Width calculation: DESC (40% terminal), SYNTAX (remaining - 25)
- Safety bounds on all width calculations
- Color coordination: cyan/yellow/magenta/green/dim
- Consistent formatting across interactive and explain modes
