Description

Render the Kanban board using bblessed widgets with optional vertical layout.

Acceptance Criteria

• [x] Columns and tasks rendered with bblessed layouts
• [x] Support horizontal and vertical modes
• [x] Works on Node and Bun

Implementation Notes

Implemented Kanban board rendering using blessed's scrollable viewer:

Key Changes:

1. Added --tui flag: Extended the board view command with an optional --tui flag for interactive viewing
2. Created board UI module: New file src/ui/board.ts with renderBoardTui() function
3. Layout Support: Maintains support for both horizontal and vertical board layouts

Technical Details:

• Created a dedicated board UI module that wraps the existing ASCII board generation
• The renderBoardTui() function:
  • Takes tasks, statuses, layout mode, and column width as parameters
  • Generates the ASCII board using the existing generateKanbanBoard() function
  • Displays the result in a blessed scrollable viewer
• This approach maximizes code reuse while adding TUI capabilities
• The scrollable viewer allows users to navigate large boards that exceed terminal dimensions

Design Decision:

• Rather than reimplementing the board layout logic with blessed widgets, we opted to reuse the existing ASCII board generation
• This keeps the implementation simple and consistent while still providing the benefits of scrollable navigation
• The ASCII art approach is actually more portable and renders consistently across different terminals

Integration:

• Modified the board view command handler to check for the --tui option
• Supports all existing board options (--vertical, --layout)
• Falls back to direct console output when blessed is unavailable or --tui is not specified
