claude-code - 💡(How to fix) Fix [FEATURE] Agent view should use available terminal height instead of truncating behind 'show more'

Problem Statement

Agent view truncates the session list and hides entries behind a "show more" fold, even when the terminal window has plenty of vertical space to display them. On a large monitor with a tall terminal, there's significant unused whitespace below the fold. Worse, after you click into a session and come back to the list, you have to expand "show more" again every time.

Two issues:

1. The visible row count doesn't adapt to terminal height. A 60-row terminal should show more sessions than a 24-row one.
2. The "show more" state resets when you navigate away and back, so you're re-expanding it constantly.

Proposed Solution

• Dynamically size the visible list based on available terminal rows (minus the input area and any chrome). Fill the space.
• Persist the expanded state so navigating into a session and back doesn't reset the fold.
