[BUG] Past Conversations panel only shows 3 sessions, cannot scroll or search history

What's Wrong?

The "Past Conversations" panel in Claude Code VSCode extension only shows 3 sessions
grouped by time (Today, Past week, Past month). Previously it showed all conversation
history. Now it's impossible to scroll down to see more sessions, and the search
function also returns no results.

65+ session files are confirmed stored in ~/.claude/projects/ but the UI only
displays 3 of them.

What Should Happen?

All past conversation sessions should be displayed in the Past Conversations panel,
with the ability to scroll through all history and search by keyword - exactly as it
worked in previous versions of Claude Code.
