fix(AIComponents): add AIConversationController for agent conversations (v14) - #3429
Merged

Conversation
…ons (v14) Port stream-chat-react-native's AIConversationController (v9-release, incl. #3974) to stream-chat-react/ai-components with the same names, state and behaviour, and give AIConversation and AIMessageComposer an optional `conversation` prop. Also fixes AIPendingMessageTracker: a question whose copy arrives in the update that first passes it no longer shows twice, and a turn that starts with a reply keeps its key when older messages load above it.

Goal
The v14 port of #3428, for the
release-v14line.Every app built on the AI components works out
messages,pendingMessage,isThinking, ratings, retries and editing itself. StreamChatAI (iOS) and stream-chat-react-native already share one conversation-state contract (AIConversation/AIConversationController). This brings the same controller to the web kit, so both JS kits read the same and an agent SDK transport (agentChatTransport) can plug into either.Implementation details
Conversation/controller/:AIConversationController,AIConversationExchange,AIAgentError+AI_AGENT_ERROR_MESSAGE,offers,types,useAIConversationState, copied from React Nativev9-release(including fix(ai-components): align agent conversations with the other SDKs stream-chat-react-native#3974). Names and behaviour are kept: send, stop, regenerate, edit/cancelEditing, retry, clearError, rate, loadOlderMessages,actions,chatOption,custom, the reply timeout and React Native's retry. A generated UI's action travels asrequest.custom.uiAction. Web adaptations only:Files; a pending message shows them through object URLs the controller makes once per file and revokes ondispose();AIMessageComposerStore, which gainsisEditing,chatOptionandcustom(newcreateAIMessageComposerStore(), React Native'screateNewComposerStore);crypto.randomUUID(with a fallback for insecure contexts), deep comparison usesreact-fast-compare,StateStorecomes fromstream-chat, anduseStateStoreis the SDK's own;AIMessagegainsrating;AI_AGENT_ERROR_MESSAGEstays English text, as in React Native; the README shows how to detect the error and show copy of your own.<AIConversation conversation={…}>: reads messages, the pending message, thinking (statussubmitted), older messages, the approver and reply actions (rating, regenerate when offered), and offers edit on the person's latest message. The existing props keep working;messagesis now optional.<AIMessageComposer conversation={…}>: uses the controller's composer store; submitting sends{ text, attachments, chatOption, custom }throughconversation.sendunlessonSubmitcallspreventDefault();SubmitButtonturns into aStopButtonwhile the agent answers, and Enter doesn't send meanwhile; an "Editing" chip with a cancel button shows whileisEditing, and the text input takes focus.ChatOptionskeeps the picked option in the store, where it stays picked across a form reset.AIPendingMessageTracker/turnsOf: ported the fixes from fix(ai-components): align agent conversations with the other SDKs stream-chat-react-native#3974. A question no longer shows twice when its copy arrives in the same update, and a turn keeps its key when older messages load above it. The new tests fail onrelease-v14.Editingandaria/Cancel editing, filled in all 12 locales (React Native's wording where it has them; German and Portuguese are new).AIConversationControllersection, including the StrictMode-safe pattern (create the controller in auseEffectanddispose()it in that effect's cleanup, neveruseState(() => new …)plus dispose).Tests: React Native's controller and exchange suites ported to Vitest (100 tests), UI tests for the controlled conversation, the composer and a StrictMode mount, and the tracker regressions.
