fix(transport): read Claude's own-row "Restart to update" banner as a status line (#2662)

CLAUDE_STATUS_WARNINGS, the exact rows that may sit under Claude's mode footer, gains one alternative: "✔ Update installed · Restart to update", the wording Claude 2.1.319 prints on its own row in a narrow pane. The pattern stays anchored at both ends and still matches "/restart to apply" and "Restart to apply" exactly, so the footer search reaches the mode footer and the draft-aware reader, activity classification and send readiness read the prompt as before; a near miss still reads unknown. The versioned banner and the /rc row were already handled. Tests add the row to the warning-footer readiness matrix and an empty, typed and near-miss composer case.
