feat(interactive): Add intuitive loop to go back to command search

Added seamless loop functionality for interactive mode:

Features:
1. Main Interactive Loop:
   - Wrapped entire interactive mode in while true loop
   - After viewing flags, prompts to search another command
   - Press Enter to return to command menu
   - Clear screen for clean UX

2. Multiple Exit Options:
   - Esc in command menu: Clean exit with goodbye message
   - Ctrl+C at prompt: Immediate exit
   - Clear, intuitive navigation

3. User Flow:
   Step 1: Select command from fuzzy search
   Step 2: View command details and syntax
   Step 3: Browse flags with fuzzy search
   Step 4: Press Enter → Back to Step 1
          OR Ctrl+C → Exit

4. Visual Feedback:
   - Clear prompt: 'Press Enter to search another command'
   - Separator lines for clarity
   - Screen clear between iterations
   - Goodbye message on exit

Benefits:
- No need to restart script for each command
- Intuitive navigation (Enter = continue, Esc/Ctrl+C = exit)
- Seamless command exploration workflow
- Better for learning/comparing multiple commands
- Professional UX with clear feedback

Example Session:
  1. User selects 'ls' → views flags
  2. Press Enter
  3. Back to command menu, selects 'grep' → views flags
  4. Press Enter
  5. Back to command menu, selects 'tar' → views flags
  6. Ctrl+C to exit

User Request: 'we also want a means to easily go back intuitively from after pulling up the fuzzy search for flags for a command back to the command fuzzy search'
