📝 Detailed Description

What does this PR do?

This PR completely rewrites the main README.md file to provide comprehensive documentation for the Predictify Contracts project, including detailed descriptions of both contracts, usage examples, build instructions, and deployment guidance.

Why is this change needed?

The existing README was minimal and lacked essential information for developers and users. The new README provides a complete overview of the project, making it easier for new contributors to understand and work with the codebase.

How was this tested?

• Reviewed the markdown formatting and links
• Verified all code examples are syntactically correct
• Confirmed project structure documentation matches actual codebase
• Tested all build commands mentioned in the README

Alternative Solutions Considered

• Adding documentation to individual contract directories (less discoverable)
• Creating separate documentation files (more complex to maintain)
• Chose to consolidate everything in the main README for better discoverability

Pull Request Overview

This PR rewrites the main README to provide a detailed project description, contract overviews, usage examples, and deployment instructions.

• Expanded project introduction and structure section
• Added “Contracts Overview” with details for hello-world and predictify-hybrid
• Included build, test, deployment, troubleshooting, resources, and license information

Comments suppressed due to low confidence (3)

README.md:1

• [nitpick] Consider updating the project title to reflect the Predictify Contracts project (e.g., # Predictify Contracts), so it matches the repository’s purpose and description.

# Soroban Project

README.md:7

• [nitpick] Since this README is quite long, adding a Table of Contents immediately after the title can help readers navigate to sections like project structure, contract overviews, and deployment instructions.

## Project Structure

README.md:81

• [nitpick] JavaScript style guides often recommend camelCase for function names. If possible, consider aligning the client API to createReflectorMarket or explicitly note that these methods use snake_case.
