Add JSON Schema for AutoRect Recursive 2D Layout Specification

[belladonnaf]

Description:

• This pull request introduces a new JSON Schema file (autorect.schema.json) for the AutoRect JSON specification. The schema defines a recursive structure for a 2D layout system used in UI component design. Key features include:

Recursive Object Structure:

• Defines an objects array where each object can have nested child objects. Each object includes properties such as id, class (an array of strings), selected (a boolean), childs (recursive array), and selection (a string).

State Management:

• Provides a detailed states object that captures positional data (e.g., x, y, pct_x, pct_y) for UI elements.

Additional Metadata:

• Includes fields such as history, various selection-related properties, and a custom_css string to support custom styling.

• The schema has been validated against the JSON Schema Draft-07 standard and is intended to facilitate easy integration with tools like JSON Schema Validator and IDE extensions. This contribution aims to standardize the format for recursive AutoRect JSON objects, making it accessible for broader adoption and ensuring consistency across implementations.
