VS Code extension session history missing old sessions

Description

The VS Code extension's session history picker does not show previously created sessions from the same VS Code extension. Sessions created from the Claude Code desktop app are visible in the desktop app's history, but VS Code sessions are not visible in the VS Code extension's session picker.

Steps to Reproduce

1. Work in a VS Code Claude Code extension session for an extended period (e.g., 10+ hours)
2. Close the session
3. Open VS Code again and check session history
4. Old VS Code sessions do not appear in the picker

Observed Behavior

• Session history in VS Code extension does not show previously created VS Code sessions
• Sessions created via Claude Code desktop app appear correctly in the desktop app's history
• The session data does exist on disk at ~/.claude/projects/<project>/ with full .jsonl conversation logs

Expected Behavior

All sessions for the current project should appear in the VS Code extension's session history, regardless of which entrypoint (VS Code, desktop, CLI) created them.
