The custom onErrorRetry existed only to honor a function-form
retryDelay, which exactly one caller (the app data provider) used for
exponential backoff. Fall back to SWR's built-in error retry and
express that caller's cadence with constant options.
Consolidate ordinary query snapshots on SWR and make Profiles own its query key, cache mutation, and invalidation policy.
Impact:
- remove the generic synchronous query Map while keeping dedicated Mihomo WebSocket snapshots
- eliminate duplicate Profiles refreshes while preserving retries and the 800 ms event throttle
- preserve preload-backed Verge updates and system proxy rollback behavior
- scope uptime polling to the Home Clash info card instead of the app lifetime
- leave RunState, Connections, Traffic, backend, and IPC contracts unchanged
- reduce frontend code by 72 net lines without adding dependencies
Replace swr with @tanstack/react-query v5 across all hooks, providers,
and components. Introduce singleton QueryClient, WS subscription pattern
via useQuery+useEffect, and enforce component-layer cache access contract.
