[github-actions]

This change involves updating dependencies in multiple project files to utilize the latest version of the zod package, removing the zod-to-json-schema package due to its deprecated functionality being integrated into zod. The code adjustments reflect these dependency changes, streamlining schema validation and JSON schema conversions.

Walkthrough

• Refactor: Upgraded zod to version 4.0.5, offering enhanced schema capabilities and stability.
• Chore: Removed zod-to-json-schema as its functionality is now directly supported by the updated zod.
• Style: Minor clean-up by removing redundant comments (eslint-disable-line) related to TypeScript no-unsafe-return errors.
• Compatibility: Ensured backward compatibility and improved efficiency in JSON schema handling without changing user-facing functionality.
