New Message component

[haydenbleasel]

This pull request consolidates the documentation for the Actions, Branch, and Response components into the main Message component documentation. This unifies the chat UI documentation, making it easier for users to understand and implement advanced chat features such as message actions, branching, and markdown rendering. The documentation now provides a comprehensive overview of all related components, updated usage examples, and detailed props tables for the entire suite.

Documentation Unification and Cleanup:

• Removed the separate Actions documentation file and merged its content into the main Message documentation, including installation, usage, features, and props.
• Removed the separate Branch documentation file and merged its details into the main Message documentation, including advanced branching features and props.
• Updated the Message documentation to include all features previously documented in Actions, Branch, and Response, providing a single source of truth for chat UI components.

Enhancements to Main Message Documentation:

• Added an overview of features such as message rendering, branching, action buttons, markdown support, accessibility, and theme integration.
• Updated the usage example to demonstrate a complete chat UI with message actions (retry/copy), markdown rendering, and conversation controls, replacing the previous minimal example.
• Expanded and unified props tables for all subcomponents (Message, MessageContent, MessageResponse, MessageActions, MessageAction, MessageBranch, etc.), improving discoverability and clarity.
• Added a required CSS import note for Streamdown styles, ensuring users apply correct styling for markdown responses.

Changelog Update:

• Added a changeset noting the merge of Actions, Branch, and Response into Message, and marking this as a minor version update for the ai-elements package.
