Hexlet tests and linter status:

The project is designed for data validation by setting specific conditions.

The current build includes the following validation types:

• String Validation: Checks content, minimum length, and presence of specified substrings.
• Number Validation: Verifies numeric type, sign, and presence within a given range.
• Map Validation: Ensures correct map data type, matches a specified size, and adheres to a validation scheme.

Additionally, it supports the validation of any eight-byte numbers, including floating-point numbers.
