The bottom-right progress panel duplicated feedback already shown by toasts. Remove it and the operation-tracking state to simplify the UI: - Delete state/session-operations.tsx and session-progress-panel.tsx. - Remove SessionOperationsProvider/SessionProgressPanel from AppShell. - Remove startOperation/completeOperation calls from useInstanceActions and ToolStarter. - Remove SessionOperationsProvider wrapper from DashboardPage.test.tsx. - Remove .session-progress-panel CSS rules. - Format use-events.test.ts mock to match project lint rules. Quality gates: npm run typecheck, npm run lint, npm test -- --run (87 passed).
