Both actions previously gave no feedback: opening a ConPTY session only created the tile after the launch-spec roundtrip (which may build a worktree), and the refine button just disappeared while the run was in flight. Add a shared Ellipse.spinner style, and let ConPtyPaneViewModel resolve its own launch spec so the tile shows up immediately with a starting overlay. A failed launch now keeps the tile with its inline error banner instead of never appearing — Start() is separated from the ctor so the host can subscribe to ErrorReported before the launch begins.
