update: "ak help" command enhanced with fzf-powered live filtering and a clean interactive UI

[maruf-pfc]

✨ Improved ak help Experience

The ak help command has been completely reworked to provide a more interactive and user-friendly experience.

🧩 Features

• Split-View TUI (Terminal UI)

  • Left panel: Live module filtering
  • Right panel: Instant command preview

• Real-Time Interaction

  • As you search or navigate modules, the corresponding commands are previewed instantly.

• Backward Compatibility

  • Existing usage such as:

    ak help <module>

    continues to work exactly as before.

• Graceful Fallback

  • If fzf is not installed, the system automatically falls back to a simpler help interface without breaking functionality.

🚀 Why This Matters

This update significantly improves discoverability and usability by allowing users to:

• Quickly explore available modules
• Preview commands without executing them
• Maintain compatibility with existing workflows

📦 Requirements

• Optional: fzf for the full interactive experience

If fzf is unavailable, the tool will still function using a non-interactive fallback mode.
