Delete deprecated MessageContentFactory

[gpunto]

🎯 Goal

Removing the deprecated MessageContentFactory before updating the message item design.

🛠 Implementation details

Remove class and all related references. All the if checks that were checking if (factory == Deprecated) were simplified to only the true branch.

🎨 UI Changes

None

🧪 Testing

Everything should work as normal

Summary by CodeRabbit

• Breaking Changes

  • Removed the deprecated MessageContentFactory class and its related APIs from public use. Applications relying on this class will need to migrate to the ChatTheme component factory approach.

• Refactoring

  • Simplified message component signatures across the library by consolidating factory parameters for improved consistency and ease of use.

Walkthrough

The PR removes the deprecated MessageContentFactory class and parameter from the public API. Message content rendering now exclusively uses ChatTheme.componentFactory, eliminating the factory parameter from multiple composable functions and simplifying branching logic across the Compose library.

Changes

Cohort / File(s)	Summary
Factory Removal stream-chat-android-compose/src/main/java/io/getstream/chat/android/compose/ui/components/messages/factory/MessageContentFactory.kt	Entire file deleted (158 lines). Removed deprecated MessageContentFactory class with public methods for composing message content (Giphy, Deleted, Text, Quoted, etc.). Class was annotated for deprecation in favor of ChatTheme.componentFactory.
Message Content Composables stream-chat-android-compose/src/main/java/io/getstream/chat/android/compose/ui/components/messages/MessageContent.kt, stream-chat-android-compose/src/main/java/io/getstream/chat/android/compose/ui/messages/list/MessageItem.kt, stream-chat-android-compose/src/main/java/io/getstream/chat/android/compose/ui/messages/list/MessageContainer.kt	Removed messageContentFactory parameter from public composables (MessageContent, MessageItem, DefaultMessageItemFooterContent, DefaultMessageItemCenterContent, RegularMessageContent, MessageContainer, DefaultMessageItem). Eliminated conditional branching and now consistently use ChatTheme.componentFactory for all message content rendering.
Message List stream-chat-android-compose/src/main/java/io/getstream/chat/android/compose/ui/messages/list/MessageList.kt, stream-chat-android-compose/src/main/java/io/getstream/chat/android/compose/ui/messages/MessagesScreen.kt	Removed messageContentFactory parameter from public MessageList() and MessagesScreen() overloads. Simplified message item composition to always use component factory without conditional logic or factory parameter passing.
Theme & Component Factory stream-chat-android-compose/src/main/java/io/getstream/chat/android/compose/ui/theme/ChatTheme.kt, stream-chat-android-compose/src/main/java/io/getstream/chat/android/compose/ui/theme/ChatComponentFactory.kt	Removed messageContentFactory parameter from ChatTheme(...) constructor. Removed ChatTheme.messageContentFactory accessor property. Removed LocalMessageContentFactory compositionLocalof declaration. Removed messageContentFactory from internal calls in ChatComponentFactory (e.g., DefaultMessageContainer, MessageListItemContainer).
Public API Surface stream-chat-android-compose/api/stream-chat-android-compose.api	Updated public API signatures to reflect removal of messageContentFactory parameters from MessageContent, MessageContainer, MessageItem, MessageList, MessagesScreen, and ChatTheme. Removed MessageContentFactory class from public surface.
