/**
 * @tag forge-ai-chatbot
 *
 * @summary A complete, self-contained AI chatbot component.
 *
 * @description
 * The AI Chatbot component provides a full-featured chat interface with support for streaming responses,
 * client-side tool execution, file attachments, markdown rendering, and programmatic control.
 * It uses an adapter pattern to abstract communication, allowing for any protocol implementation.
 *
 * @slot header - Slot for custom header content
 * @slot icon - Slot for custom header icon (default: forge-ai-icon)
 * @slot header-actions - Slot for custom header action buttons (rendered before built-in header actions)
 * @slot empty-state-icon - Slot for custom empty state icon
 * @slot empty-state - Slot for custom empty state content (overrides default suggestions)
 *
 * @property {string} titleText - The title text to display in the header (default: 'AI Assistant')
 * @property {HeadingLevel} headingLevel - Controls the heading level for the title content (default: 2)
 * @property {string | null | undefined} disclaimerText - The disclaimer text to display below the prompt. Set to empty string, null, or undefined to hide.
 * @property {boolean} showConversationsButton - Controls conversations button visibility (default: false)
 * @property {AgentInfo} agentInfo - Agent metadata for info dialog
 * @property {Agent[]} agents - List of available agents for selector
 * @property {Suggestion[]} suggestions - Suggestions to display in the empty state
 *
 * @cssproperty --forge-ai-chatbot-icon-color - The fill color for the AI icon. Defaults to `tertiary`.
 * @cssproperty --forge-ai-chatbot-suggestion-background - The background color for suggestion buttons. Defaults to `tertiary-container`.
 * @cssproperty --forge-ai-chatbot-suggestion-foreground - The text color for suggestion buttons. Defaults to `on-tertiary-container`.
 *
 * @event {CustomEvent<void>} forge-ai-chatbot-connected - Fired when adapter connects
 * @event {CustomEvent<void>} forge-ai-chatbot-disconnected - Fired when adapter disconnects
 * @event {CustomEvent<void>} forge-ai-chatbot-run-started - Fired synchronously when a run starts, before the request is sent. Use this to set adapter context just-in-time.
 * @event {CustomEvent<ForgeAiChatbotMessageEventData>} forge-ai-chatbot-message-sent - Fired when user sends a message
 * @event {CustomEvent<ForgeAiChatbotMessageEventData>} forge-ai-chatbot-message-received - Fired when assistant message is complete
 * @event {CustomEvent<ForgeAiChatbotToolCallEventData>} forge-ai-chatbot-tool-call - Fired when a tool needs to be executed
 * @event {CustomEvent<ForgeAiChatbotErrorEventData>} forge-ai-chatbot-error - Fired when an error occurs
 * @event {CustomEvent<void>} forge-ai-chatbot-expand - Fired when header expand button is clicked
 * @event {CustomEvent<void>} forge-ai-chatbot-minimize - Fired when header minimize button is clicked
 * @event {CustomEvent<void>} forge-ai-chatbot-clear - Fired when header clear option is selected (cancelable, prevents clearMessages() if default prevented)
 * @event {CustomEvent<void>} forge-ai-chatbot-info - Fired when header info option is selected
 * @event {CustomEvent<ForgeAiChatbotResponseFeedbackEventData>} forge-ai-chatbot-response-feedback - Fired when user provides feedback on a response (thumbs up/down)
 * @event {CustomEvent<ForgeAiChatbotAgentChangeEventData>} forge-ai-chatbot-agent-change - Fired when user changes agent from the header
 * @event {CustomEvent<void>} forge-ai-chatbot-thread-state-change - Fired when there is a change to the thread state (messages, files, selected agent, etc). Use this to capture the latest thread state for persistence.
 * @event {CustomEvent<void>} forge-ai-chatbot-conversations-open - Fired when conversations panel opens
 * @event {CustomEvent<void>} forge-ai-chatbot-conversations-close - Fired when conversations panel closes
 * @event {CustomEvent<ForgeAiChatbotConversationSelectEventData>} forge-ai-chatbot-conversation-select - Fired when user selects a conversation thread
 * @event {CustomEvent<void>} forge-ai-chatbot-new-chat - Fired when user clicks new chat button (cancelable)
 * @event {CustomEvent<ForgeAiChatbotConversationSearchEventData>} forge-ai-chatbot-conversation-search - Fired when search query changes in conversations panel (debounced, cancelable)
 * @event {CustomEvent<ForgeAiChatbotConversationLoadMoreEventData>} forge-ai-chatbot-conversation-load-more - Fired when scrolling near bottom in recent chats or search chats. Query field differentiates contexts.
 * @event {CustomEvent<ForgeAiChatbotConversationRenameEventData>} forge-ai-chatbot-conversation-rename - Fired when user renames a conversation thread. Cancelable - if prevented, call onSuccess() to commit or onError() to revert.
 * @event {CustomEvent<ForgeAiChatbotConversationDeleteEventData>} forge-ai-chatbot-conversation-delete - Fired when user deletes a conversation thread. Cancelable - if prevented, call onSuccess() to commit deletion or onError() to revert. Otherwise optimistically removed.
