fix(deps): remove wildcard @askable-ui/core devDependency from svelte and vue packages #271

Summary

Both packages/svelte/package.json and packages/vue/package.json list @askable-ui/core in both dependencies (correctly pinned to ^0.12.0) and devDependencies (as "*" — any version).

The wildcard can resolve a different version of core during development and test runs than what consumers install, masking version-compatibility bugs.

Fix

Remove the "@askable-ui/core": "*" entry from devDependencies in both packages. The dependencies entry is sufficient.

// packages/svelte/package.json and packages/vue/package.json
  "devDependencies": {
-   "@askable-ui/core": "*",
    ...
  }

The React package correctly omits the wildcard already.
