- Add SessionOperationsContext + SessionProgressPanel for global, non-blocking lifecycle progress (create/start/stop/restart/delete/ recreate-tunnel) driven by SSE events. - Promote SessionsContext to authoritative shared session state with refresh, addOrUpdateSession, and removeSession helpers. - Wire AppShell, DashboardPage, SessionsPage, useInstanceActions, ToolStarter, and InstanceList into shared state so lists update immediately after create/delete without manual refresh. - Remove legacy blocking overlays from CreateSessionForm, SessionCard, and InstanceList; keep disabled states and inline spinners only. - Update DashboardPage tests to wrap with SessionsProvider and SessionOperationsProvider. - Add .cache/ to .gitignore. Quality gates: npm run typecheck, npm run lint, npm test -- --run (82 passed).
