Description

Pull request overview

This PR implements no-code SDK file-based initialization by introducing the MoEngageModule.Item protocol conformance, enabling automatic plugin discovery and initialization without explicit code. The implementation refactors the initialization architecture from imperative to event-driven, adds automated version constant generation, and improves build script organization.

• Implements MoEngageModule.Item protocol for event-driven initialization
• Adds automated version constant generation for both SPM and CocoaPods builds
• Refactors delegate setup from imperative calls to event-driven callbacks

[nitpick] The version file generation in post_build.rb (lines 59-66) uses a different format than the podspec's prepare_command (lines 46-48). The podspec uses echo with explicit \n newlines, while post_build.rb uses a heredoc. Consider using the same approach in both places for consistency. The heredoc approach in post_build.rb is cleaner and more readable, so consider updating the podspec to match this style.
