[BUG] Agent View (via double-click left arrow) Esc exit causes CLI hang and terminal misalignment

What's Wrong?

When running Claude Code in Windows 11 CMD, after entering the CLI via the claude command, double-clicking the left arrow key to open the Agent View and then pressing Esc causes Claude to hang for several seconds on the normal transcript before exiting entirely. Additionally, CMD exhibits terminal rendering/display misalignment artifacts after this sequence. However, launching directly into Agent View via claude agents and then exiting does not reproduce the display misalignment issue.

What Should Happen?

Pressing Esc in Agent View launched by claude should dismiss the view and return to the normal chat interface without exiting Claude Code or causing any terminal rendering corruption.

Additional Information

• The display misalignment only occurs when entering Agent View from the standard claude command flow, not from claude agents directly
• Suspected root cause may be incomplete terminal state restoration (e.g., cursor position, alternate screen buffer) when transitioning between views via the claude entry point
