Feature request: group Codex VS Code thread history by project/workspace

What problem are you seeing?

In the Codex VS Code extension, thread/history entries from all projects appear mixed together. When I work across multiple repositories, it becomes difficult to find the right conversation, and the history view does not clearly separate or filter threads by project/workspace.

This is especially painful for daily development because different projects often have similar task titles, files, or prompts. The current experience makes the history feel cluttered and easy to misread.

What would you like to see?

Please add project/workspace-aware history organization for the Codex VS Code extension, for example:

• Group thread history by workspace root / repository.
• Show the project or workspace name prominently in each history item.
• Add a filter such as "Current workspace only".
• Keep an optional "All projects" view for users who want global history.
• Ideally support search by project name, repo path, or thread title.

Why this matters

Codex is used inside concrete codebases. The thread history should preserve that context, otherwise conversations from unrelated projects get mixed together and become hard to trust or reuse.
