feat(ui): "Worktree öffnen" im Kontextmenü der Task-Zeile

Group 1 of the task-row context menu gets a fourth gated entry, right after "Open interactive session": it opens the task's worktree folder via Process.Start/UseShellExecute, mirroring ListsIslandViewModel's OpenInExplorer. Missing worktree greys the item out with a tooltip reason instead of hiding it, keeping Group 1's fixed length. Failures report through TasksIslandViewModel.ErrorReported (footer strip), not a silent catch.
