"Open in" on an isolated run opened the anchor worktree as a plain folder, so the other repos were missing from the editor. The worktree fan-out now writes a copy of the project's .code-workspace into the per-thread directory, with each repo folder pointed at its worktree and non-repo folders left at their original path. The client opens that copy for fanned-out threads. Threads created before this have no copy, so the launcher falls back to the directory when the workspace file is missing. Fixes #125

What Changed
The isolated-run worktree fan-out now writes a copy of the project's
.code-workspaceinto the per-thread directory (<worktreesDir>/<projectId>/<threadId>/<name>.code-workspace). Each repo folder in the copy points at that thread's worktree (as a relative path); folders that aren't repos, like adocsdir, keep their original absolute path.settingsand other keys carry over."Open in" hands that copy to workspace-aware editors when the thread has fanned-out worktrees. Client and server derive its path with one shared helper,
threadWorkspaceFilePathinpackages/shared/src/path.ts.Threads created before this have no copy on disk, so the editor launcher now checks the workspace file exists and falls back to the directory instead of a failed open.
The file lives in the per-thread directory, so it goes when that directory does. No extra cleanup code.
Why
Fixes #125. For a
.code-workspaceproject, "Open in" on an isolated run opened only the anchor worktree as a plain folder, so the other repos were missing from the editor. Pointing at the project's own workspace file would have opened the original checkouts instead of the thread's worktrees.Verified:
path.test.ts,WorktreeFanout.test.tsandexternalLauncher.test.tspass; server and web typecheck clean. In a real dev build, an isolated run opens asshop (Workspace)with every repo, and a pre-fix thread still opens its anchor folder with no error.UI Changes
