This pull request refactors and improves the validation and utility functions for working with Roman numerals. The main focus is on centralizing input validation, improving error handling, and adding new utility features. Additionally, the test suite is updated to cover new edge cases and functionalities.

Core improvements and new features:

Centralized validation and code simplification:

• Introduced a new validateGeneral function to centralize and standardize validation for all general (string or number) inputs, replacing repetitive validation code across multiple functions (range, random, etc.). This reduces code duplication and ensures consistent error handling for invalid or out-of-range values. [1] [2]
• Refactored range, random, and related functions to use validateGeneral for input validation, simplifying their logic and improving maintainability. [1] [2] [3] [4]

New utility function:

• Added a new table function that generates an array of objects mapping numbers to their Roman numeral representations within a specified range, with full validation. [1] [2]

Improved error handling and edge case coverage:

• Enhanced sum and diff functions to throw descriptive errors when results exceed the allowed range (over 3999 or below 1). [1] [2] [3] [4]
• Updated multiply, max, and min to use more robust input validation, only operating on valid Roman numerals and handling errors gracefully. [1] [2] [3] [4]

Test suite improvements:

• Expanded tests to cover the new validation logic, edge cases for sum/diff out-of-range errors, and added tests for the new table function and validateGeneral. [1] [2] [3]

Type and documentation updates:

• Updated TypeScript types and JSDoc comments for clarity and accuracy, especially for validation and utility functions. [1] [2]

These changes make the codebase more robust, maintainable, and user-friendly when working with Roman numeral utilities.
