VS Code extension /resume returns empty despite valid transcripts on disk

Extension: v2.1.133, Windows

/resume and the "Past Conversations" picker return an empty list, even though valid <uuid>.jsonl transcripts exist in the project's ~/.claude/projects/<encoded-key>/ directory.

Extension log shows the request firing without error:

Received message from webview: {"type":"list_sessions_request"}
Fetched 0 remote sessions

No errors surfaced. Workspace is on a mapped Windows network drive, which may be related (path encoding mismatch between writes and the picker's lookup).
