Summary of Changes

Hello @allenhutchison, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on refactoring the Zod validation utilities within the workspace-server by introducing a generic helper function. This helper encapsulates the common logic for parsing Zod schemas and handling validation errors, thereby streamlining the implementation of specific validation functions like those for email, datetime, and document IDs. The change aims to enhance code readability and maintainability by reducing boilerplate.

Highlights

• New Generic Validator Helper: A new private helper function, createValidator, has been introduced to centralize the common pattern of Zod schema parsing and error handling.
• Refactored Validation Functions: The existing validateEmail, validateDateTime, and validateDocumentId functions have been refactored to utilize the new createValidator helper, reducing code duplication and improving consistency.
• Improved Maintainability: This refactoring makes the validation utilities more concise and easier to maintain by abstracting the repetitive try-catch blocks for Zod errors.

Code Review

This is an excellent refactoring that significantly reduces code duplication by extracting the common Zod validation logic into a generic createValidator helper function. The code is now more maintainable and easier to read. I have one suggestion to further improve the type clarity of the new helper function.
