The existing README.md provided basic commands for executing build flavors but lacked documentation regarding Gradle Wrapper supply-chain security. Because the gradle-wrapper.jar is a binary blob checked directly into the repository, it represents a high-value target for supply-chain compromises. If a malicious dependency or PR modifies this binary, it can result in arbitrary code execution during local builds or CI/CD pipelines.
closes #302
🛠️ Solution
Enhanced the build documentation section of the README.md by appending a comprehensive guide on Gradle Wrapper Security & Verification.
The additions include:
Risk Assessment: A concise breakdown of why wrapper validation is critical to prevent malicious code injection.
Manual Verification Steps: Step-by-step instructions for engineers to audit and verify the wrapper's SHA-256 checksum against official Gradle release hashes.
Automated CI/CD Safeguards: Documentation on integrating the official Gradle Wrapper Validation Action (gradle/wrapper-validation-action) into GitHub Actions workflows to automatically block unauthorized or compromised wrapper binaries from being merged.

✅ Impact & Benefits
Stronger Security Posture: Educates contributors on safe repository interactions and local build safety.
Automated Defense: Sets the blueprint for adding automated validation to the project's CI pipelines, preventing malicious commits from slipping through silently.
