Problem Statement

Using the VS Code extension, if I open up a Claude Code chat session and type out a message to send later, then VS Code crashes or exists for any reason, that drafted session is lost forever. The chat tabs are restored, but any un-sent content is lost. It would be nice to retain those drafts in some sort of local storage.

Proposed Solution

Restore drafted chat messages on re-launch
