fix: resolve frontend data race conditions in hooks

- use-system-state: convert module-level `disablingTunMode` to useRef
  to isolate state per hook instance, fix no-op clearTimeout, add
  proper effect cleanup
- use-profiles: convert forEach to for..of so selectNodeForGroup is
  properly awaited, remove fire-and-forget setTimeout around mutate
- use-clash: add useLockFn to patchInfo for concurrency safety
