VS Code extension: sidebar session list doesn't reflect true recency without a manual window reload

Describe the bug
The Claude Code sessions list in the Activity Bar sidebar doesn't reliably sort/refresh to reflect which session is actually most recently active. An in-progress session can sit buried below older, inactive ones. The only fix I've found is Developer: Reload Window — but per #94743, that restarts the extension host and kills any in-flight session/background work, so it's a costly workaround for what should be a cosmetic refresh.

Expected behavior

• The sidebar list re-sorts by actual recency without requiring a full window reload, or
• A lightweight "refresh list" action (icon/command) that re-syncs the sidebar's order without restarting the extension host / interrupting live sessions.

Environment

• Claude Code VS Code extension (version TBD)
• VS Code version: TBD
• OS: macOS
