`CopilotChatConfigurationProvider` is a React context provider that manages configuration for chat UI components,
including labels, agent ID, and thread ID. It enables customization of all text labels in the chat interface and
provides context for chat components to access configuration values.

## What is CopilotChatConfigurationProvider?

The CopilotChatConfigurationProvider:

- Manages UI labels for all chat components (placeholders, button labels, etc.), allowing for localization or
  customization of the chat interface.
- Lets you to access the current `agentId` and `threadId`
- Supports nested configuration with proper inheritance

## Basic Usage

Wrap your chat components with the provider to customize configuration:

```tsx
import { CopilotChatConfigurationProvider } from "@copilotkit/react-core";

function App() {
  return (
    <CopilotChatConfigurationProvider
      threadId="main-thread"
      agentId="assistant"
      labels={{
        chatInputPlaceholder: "Ask me anything...",
        assistantMessageToolbarCopyMessageLabel: "Copy response",
      }}
    >
      {/* Your chat components */}
    </CopilotChatConfigurationProvider>
  );
}
```

## Props

### threadId

`string` **(required)**

A unique identifier for the conversation thread. This is used to maintain conversation history and context.

```tsx
<CopilotChatConfigurationProvider threadId="conversation-123">
  {children}
</CopilotChatConfigurationProvider>
```

### agentId

`string` **(optional)**

The ID of the agent to use for this chat context. If not provided, defaults to `"default"`.

```tsx
<CopilotChatConfigurationProvider
  threadId="thread-1"
  agentId="customer-support"
>
  {children}
</CopilotChatConfigurationProvider>
```

### labels

`Partial<CopilotChatLabels>` **(optional)**

Custom labels for chat UI elements. Any labels not provided will use the default values.

```tsx
<CopilotChatConfigurationProvider
  threadId="thread-1"
  labels={{
    chatInputPlaceholder: "Type your message here...",
    chatDisclaimerText: "AI responses may contain errors.",
    assistantMessageToolbarRegenerateLabel: "Try again",
  }}
>
  {children}
</CopilotChatConfigurationProvider>
```

### children

`ReactNode` **(required)**

The React components that will have access to the chat configuration context.

## Using with CopilotChat

The `CopilotChat` component automatically creates its own `CopilotChatConfigurationProvider` internally. When using
`CopilotChat`, you can pass configuration directly as props:

```tsx
<CopilotChat
  threadId="main-thread"
  agentId="assistant"
  labels={{
    chatInputPlaceholder: "How can I help you today?",
  }}
/>
```

### Priority System

When `CopilotChat` is used within an existing `CopilotChatConfigurationProvider`, values are merged with the following
priority (highest to lowest):

1. Props passed directly to `CopilotChat`
2. Values from the outer `CopilotChatConfigurationProvider`
3. Default values

Example:

```tsx
<CopilotChatConfigurationProvider agentId="outer-agent">
  <CopilotChat
    threadId="inner-thread"
    // agentId inherits from outer: "outer-agent"
  />
</CopilotChatConfigurationProvider>
```

## Accessing Configuration

Use the `useCopilotChatConfiguration` hook to access configuration values in your components:

```tsx
import { useCopilotChatConfiguration } from "@copilotkit/react-core";

function MyComponent() {
  const config = useCopilotChatConfiguration();

  if (!config) {
    // No provider found
    return null;
  }

  return (
    <div>
      <p>Agent: {config.agentId}</p>
      <p>Thread: {config.threadId}</p>
      <p>Labels: {JSON.stringify(config.labels)}</p>
    </div>
  );
}
```

Note: The hook returns `null` if no provider is found in the component tree.

## Localization Example

The provider is ideal for implementing localization:

```tsx
import { useTranslation } from "react-i18next";

function LocalizedChat() {
  const { t } = useTranslation();

  return (
    <CopilotChatConfigurationProvider
      threadId="chat-1"
      labels={{
        chatInputPlaceholder: t("chat.input.placeholder"),
        assistantMessageToolbarCopyMessageLabel: t("chat.assistant.copy"),
        assistantMessageToolbarThumbsUpLabel: t("chat.assistant.thumbsUp"),
        assistantMessageToolbarThumbsDownLabel: t("chat.assistant.thumbsDown"),
        userMessageToolbarEditMessageLabel: t("chat.user.edit"),
        chatDisclaimerText: t("chat.disclaimer"),
      }}
    >
      <CopilotChat />
    </CopilotChatConfigurationProvider>
  );
}
```
