fix: add error logging to AsyncStorage catch blocks

[gugli4ifenix-design]

Problem

makeAsyncStorage.ts has 8 empty catch blocks that silently swallow all AsyncStorage errors:

try {
  persistedData = await AsyncStorage.getItem(dataKey);
} catch (_err) {} // all errors silently lost

If AsyncStorage fails (permissions, full disk, corrupted data), persisted data is silently lost with no indication to the developer.

Fix

Add console.warn guarded by __DEV__ — errors are logged during development, production behavior unchanged:

} catch (_err) {
  if (__DEV__) console.warn("[urql] AsyncStorage error:", _err);
}

• 8 catch blocks updated in packages/storage-rn/src/makeAsyncStorage.ts
• Production safe — no logging in release builds
• Behavior unchanged — still fails silently, but developers can now see why

I think this should at least have an onError option, as the examples you gave are valid, but would likely require developer intervention in shipped apps to inform users or to have a way to recover from these errors.

Let me know if you're still interested in picking this up, otherwise happy to push a patch to this branch to get this shipped
