VS Code extension: /resume shows no conversations while terminal mode works

Description

The /resume command in the VS Code graphical extension shows no conversations, while the same command works correctly in terminal mode. Additionally, Claude Code tabs no longer restore when reopening VS Code (previously worked before the Nov 27 update).

Environment

• Claude Code version: 2.0.55
• VS Code version: 1.106.3
• Platform: Linux (Ubuntu, kernel 6.8.0-88-generic)
• Extension path: ~/.vscode/extensions/anthropic.claude-code-2.0.55-linux-x64

Steps to Reproduce

1. Have previous conversations in Claude Code
2. Open VS Code with Claude Code extension
3. Use /resume command in the graphical Claude Code panel
4. No conversations are listed

Expected Behavior

• /resume should list previous conversations (as it does in terminal mode)
• Claude Code tabs left open should restore when reopening VS Code

Actual Behavior

• /resume shows nothing in graphical mode
• Previous conversations are not accessible from the VS Code extension
• Session files exist in ~/.claude/projects/ and work correctly in terminal mode

Additional Context

• This regression started after the Nov 27, 2025 update (version 2.0.55)
• Terminal mode (claude command) works correctly and can resume conversations
• Session history files are present and valid in ~/.claude/projects/
• The history.jsonl file contains recent entries
