refactor!: internalize shared code and prepare for archive

Removes the 'shared' module and duplicates its utility classes into 'maps-rx' and 'places-rx' as internal extensions.

This change eliminates the need for a separate 'shared' Maven artifact, allowing 'maps-rx' and 'places-rx' to be used as standalone libraries without complex transitive dependencies for manual AAR consumers. Code duplication was chosen over a shared artifact to simplify distribution as we prepare to archive these libraries.

Key changes:
- Deleted 'shared' module and updated settings.gradle.
- Copied MainThreadObservable and related utilities to 'com.google.maps.android.rx.maps.internal' and 'com.google.maps.android.rx.places.internal'.
- Updated all imports to use the local internal versions.
- Removed project dependency on ':shared' from build files.
- Marked all duplicated code as 'internal' to prevent binary compatibility issues or duplicate class definitions if both libraries are used together.

This refactoring streamlines the project structure in anticipation of archiving the repository.

 # Maps Android Rx
 
+# ⚠️ PROJECT ARCHIVED & DEPRECATED ⚠️
+
+**This library is no longer maintained and has been officially archived.**
+
+### Why is this project being retired?
+
+Since the launch of this project, the Android ecosystem has largely transitioned from RxJava to 
+**Kotlin Coroutines and Flows**. In alignment with modern Android development practices, 
+maintenance effort has shifted to libraries that natively support these features.
+
+### Alternatives and Migration
+
+1. **Maps SDK for Android KTX:** We recommend using the
+[Maps SDK for Android KTX](https://github.com/googlemaps/android-maps-ktx). This is the current 
+standard for idiomatic Kotlin development and provides native support for **Coroutines** and **Flow**.
+2. **Bridging to RxJava:** If your codebase remains strictly RxJava-based, you can use the Maps KTX
+library and convert the resulting Flows into Observables using the [Kotlinx Coroutines RxJava bridge](https://github.com/Kotlin/kotlinx.coroutines/tree/master/reactive/kotlinx-coroutines-rx3).
+3. **Source Access:** The source code for these Rx wrappers remains available in this repository for
+reference or manual inclusion in your project. However, no further updates, bug fixes, or dependency
+bumps will be performed.
+
+---
+
+### Final Maintenance Note
+
+This project is being archived to provide clarity to the developer community and to ensure users are
+directed toward the most active and supported tools for the Maps SDK.
+
 ## Description
 
 This repository contains RxJava bindings for the [Maps SDK for Android](maps-sdk) and [Places SDK for Android](places-sdk).
