fix(ai-components): document a StrictMode-safe controller lifecycle and custom.uiAction - #3975

Conversation
…and custom.uiAction Create AIConversationController in the effect that disposes it, so React StrictMode's cleanup-then-rerun doesn't leave the views with a disposed controller. Document that a generated-UI action travels on AIConversationRequest.custom.uiAction, and add a Conversation state section to the ai-components README. The Expo agent examples turn off edit and regenerate: the agents router keeps the conversation in Stream Chat and can't rewind it.

What
AIConversationControllerdoc + new README "Conversation state" section: create the controller insideuseEffect, dispose it and clear state in the cleanup, render nothing until it exists. The previoususeState(() => new …)+ dispose-on-cleanup example breaks under React StrictMode (cleanup disposes the controller, the remount keeps using it).AIConversationRequest.custom.uiAction(types and README). Docs only, no runtime change.actions: { edit: false, regenerate: false }: the Stream Agents router can't rewind a conversation, so edit and regenerate would just re-ask as a new question.The two Expo examples create controllers in an event handler and dispose the previous one on switch, so they don't have the StrictMode bug.
