Transition TUI from tview to Bubble Tea

This PR introduces a significant overhaul of the terminal user interface by transitioning from tview to bubbletea. This change provides a more modern and flexible foundation for building the UI, leveraging the Elm Architecture (TEA) for better state management and component composition.

Key Changes

• New TUI Framework: Replaced tview with bubbletea, lipgloss for styling, and bubbles for common UI components.
• Enhanced UI Components:
  • A new SQL editor using textarea for a more natural editing experience.
  • A database tree view powered by tree-bubble for easier navigation.
  • Improved result set rendering with better table formatting and support for large data sets.
  • Asynchronous data fetching (metadata, tables, queries) to ensure the UI remains responsive during long-running operations.
• Refactored Architecture: Updated the application's core logic in pkg/app and pkg/command to integrate with the new TUI model and handle state transitions more effectively.
• Updated Assets: Refreshed screenshots in the screenshots/ directory to reflect the new aesthetic and layout.

The goal of this migration is to improve the maintainability of the TUI and provide a more polished, responsive, and customizable user experience for dblab.

Suggestion for logo display:
The logo appears oversized and not centered within the terminal viewport. Consider reducing its dimensions and centering it to make better use of the available terminal space. This would improve the overall visual balance and readability of the output.
