VS Code: Session history dropdown missing after recent update

Description

The session history dropdown in the VS Code extension stopped appearing after a recent update (updated ~17 hours ago from the time of this report, around 2026-03-18).

Rolling back to version 2.1.76 restores the session history dropdown functionality.

Steps to Reproduce

1. Update the Claude Code VS Code extension to the latest version (post-2.1.76)
2. Open the Claude Code panel in VS Code
3. Try to access session history — the dropdown does not appear at all
4. Only the option to edit the current session name is available

Expected Behavior

A dropdown should appear allowing the user to pick from previous session history (as it did in version 2.1.76 and earlier).

Actual Behavior

The session history dropdown does not appear. Only the current session name can be edited.

Workaround

Roll back to version 2.1.76 (Extensions panel → Claude Code → gear icon → "Install Another Version..." → 2.1.76).

Note: Terminal CLI claude --resume / --continue still works correctly — only the VS Code extension UI is affected.

Environment

• VS Code on macOS (Darwin 24.6.0)
• Working version: 2.1.76
• Broken version: the update released ~2026-03-18
