Restructure project and update CI workflows

Removed legacy configuration, scripts, and code related to the previous project structure, including old Android and iOS modules, React Native config, and various setup files. Introduced new GitHub Actions workflows for Android and iOS builds, added release workflow, and updated .gitignore and project metadata. Migrated Android and iOS source files to new locations and updated example app structure to match new module organization.
