usePresetHydration

The usePresetHydration hook (hooks/usePresetHydration.ts) fetches all saved presets from the Convex backend and populates usePresetStore.

One-Shot Strategy

This hook is called at the (create-commit)/_layout.tsx level. By running at the layout mount, it guarantees that all child spoke screens have instant access to presets. The isHydrated flag on the store prevents redundant fetches on subsequent navigations within the wizard flow.
