 * React Error Boundary that catches rendering errors in East UI components.
 * Displays EastError details (including source locations) using StatusDisplay.
 *
 * @remarks
 * `componentDidUpdate` clears the error when `children` changes, so a
 * transient render exception followed by a successful re-render shows up
 * as a brief "flash" of the error UI. We always `console.error` the caught
 * exception so the failure is preserved even when the visual flash is too
 * fast to read.
