Support multiple folders in one project (multi-root workspaces)

[baanish]

Request

Support multiple folders in a single T3 Code project, with one agent thread able to work across the selected folders. Think VS Code-style multi-root workspaces, rather than just grouping separate projects in the sidebar.

My use case

Managing my OpenClaw setup frequently requires context from both my clawd and clawdbot folders and changes across both at the same time. I need the agent to use both folders together in a single thread, not treat them as separate tasks.

Expected behavior

• Add or remove folders from a project, including folders in different locations.
• Let one thread use context from all selected folders and make coordinated changes across them, within the configured permissions.
• Clearly identify which folder each file or change belongs to.
• Where folders contain separate Git repositories, show changes grouped by repository rather than losing Git visibility by opening a shared parent folder.
• Support ordinary folders too, not just Git repositories, and preserve the existing single-folder workflow.

A useful first version could simply save a project's selected folders and make them available within one thread. Importing .code-workspace files would be a nice addition, but isn't essential to the core request.

Related discussion

Discussion #7041, converted from issue #1453, already raises the multi-repo use case. This adds my concrete OpenClaw example and emphasizes multi-folder support even when not every folder is a Git repository. I'm happy for this to be consolidated into that thread.

Closing as a duplicate of #7041 — same multi-root / multi-folder workspace request. Please continue there (your OpenClaw example and non-git folder notes are welcome on that thread).
