Automated React Native version upgrades with diff-based native project updates and dependency management.

• Fetches and applies unified diffs from the React Native Upgrade Helper, handling version bumps across package.json, iOS, and Android native files
• Maps template paths and identifiers (RnDiffApp, com.rndiffapp) to your actual project structure before applying changes
• Detects conflicts between template changes and project customizations, presenting a merge plan for manual review before applying
• Scans third-party native libraries for React Native version compatibility tables and proposes compatible dependency updates alongside the core upgrade
