feat(verification): integrate Zod validation and React Hook Form resolver for manifest inputs

[QueenColly]

Summary
This PR resolves #428 by implementing a robust Zod validation schema for the Manifest Generator inputs and integrating it with React Hook Form via the @hookform/resolvers/zod resolver.

Changes Proposed

Created manifest.schema.ts defining strict validation rules for title, description, version (semantic versioning check), and author.

Configured React Hook Form to use the Zod resolver, ensuring validation errors are cleanly intercepted before submission and rendered directly beneath the corresponding fields.

Acceptance Criteria Checklist

[x] Create a Zod schema for the manifest data.

[x] Integrate with React Hook Form resolver.

[x] Validation errors display correctly under fields.

Closes #428
