- sessionStore.applyEvent: on ui_request set currentPhase normalized from the
descriptor's phase to its short id (e.g. "F4_schema_linking" -> "F4"), so
WorkflowBar actually highlights the active phase; falls back to the existing
phase when the descriptor has none. setPhase kept for resume/getSession.
- Add pushToast store action; WidgetHost wraps postResponse in try/catch,
pushes an error toast and keeps the widget pending on failure (clearPending
only on success) so the user can retry.
- Tests: store currentPhase normalization + no-phase passthrough + pushToast;
new WorkflowBar.test.tsx asserting the matching phase is highlighted.
