harukin-expo-dev-env a809d287a2 fix: eliminate UX flash by calling setStrings() immediately in observer ...

The 100ms pure-debounce approach caused a visible layout flash on every
render (normal mode too) because Tokyo UX was not applied for 100ms.

Fix: call setStrings() immediately in the MutationObserver callback to
prevent any flash, AND keep a 250ms delayed follow-up call to catch
async train re-renders from mock XHR setTimeout(0) responses.
