[FEATURE] Allow expanding collapsed task list in CLI UI

Preflight Checklist

• [x] This is a single feature request (not multiple features)

Problem Statement

Description:

When using the TaskCreate tool to track multiple tasks, the CLI collapses pending tasks with a +N pending summary that cannot be expanded. There is no built-in way to view the full list of pending tasks within the CLI
interface.

Current behavior:

• Tasks beyond a certain count are collapsed as … +5 pending
• Clicking on the collapsed area does nothing
• /tasks is not a recognized built-in command
• The only workaround is to ask Claude to list tasks via the TaskList tool, which requires an extra conversational turn

Proposed Solution

Expected behavior:

• Provide a way to expand the collapsed task list, e.g.:
• Click on +N pending to toggle the full list
• Support a /tasks slash command that displays all tasks with their status
• Add a keyboard shortcut to expand/collapse the task panel

Why this matters:

Task lists are most useful when users can quickly see what's pending and what's in progress. The current collapse behavior hides information that users explicitly created to track progress, forcing them to take an extra step
just to see their own task list.
