/**
*
* ATTACHMENTS
*
* Components for displaying and managing different attachment types in chat messages.
* Supports two operational modes:
* - **Readonly mode**: For displaying stored attachments in sent messages (DatabaseMessageExtra[])
* - **Editable mode**: For managing pending uploads in the input form (ChatUploadedFile[])
*
* The attachment system uses `getAttachmentDisplayItems()` utility to normalize both
* data sources into a unified display format, enabling consistent rendering regardless
* of the attachment origin.
*
*/
/**
* **ChatAttachmentsList** - Unified display for file attachments in chat
*
* Central component for rendering file attachments in both ChatMessage (readonly)
* and ChatForm (editable) contexts.
*
* **Architecture:**
* - Delegates rendering to specialized thumbnail components based on attachment type
* - Manages scroll state and navigation arrows for horizontal overflow
* - Integrates with DialogChatAttachmentPreview for full-size viewing
* - Validates vision modality support via `activeModelId` prop
*
* **Features:**
* - Horizontal scroll with smooth navigation arrows
* - Image thumbnails with lazy loading and error fallback
* - File type icons for non-image files (PDF, text, audio, etc.)
* - MCP prompt attachments with expandable content preview
* - Click-to-preview with full-size dialog and download option
* - "View All" button when `limitToSingleRow` is enabled and content overflows
* - Vision modality validation to warn about unsupported image uploads
* - Customizable thumbnail dimensions via `imageHeight`/`imageWidth` props
*
* @example
* ```svelte
* <!-- Readonly mode (in ChatMessage) -->
* <ChatAttachmentsList attachments={message.extra} readonly />
*
* <!-- Editable mode (in ChatForm) -->
* <ChatAttachmentsList
* bind:uploadedFiles
* onFileRemove={(id) => removeFile(id)}

*
*/
/**
* **ChatForm** - Main chat input component with rich features
*
* The primary input interface for composing and sending chat messages.
* Orchestrates text input, file attachments, audio recording, and MCP prompts.
* Used by ChatScreenForm and ChatMessageEditForm for both new conversations and message editing.
*
* **Architecture:**
* - Composes ChatFormTextarea, ChatFormActions, and ChatFormPromptPicker
* - Manages file upload state via `uploadedFiles` bindable prop
* - Integrates with ModelsSelector for model selection in router mode
* - Communicates with parent via callbacks (onSubmit, onFilesAdd, onStop, etc.)
*
* **Input Handling:**
* - IME-safe Enter key handling (waits for composition end)
* - Shift+Enter for newline, Enter for submit
* - Paste handler for files and long text (> {pasteLongTextToFileLen} chars → file conversion)
* - Keyboard shortcut `/` triggers MCP prompt picker
*
* **Features:**
* - Auto-resizing textarea with placeholder
* - File upload via button dropdown (images/text/PDF), drag-drop, or paste
* - Audio recording with WAV conversion (when model supports audio)
* - MCP prompt picker with search and argument forms
* - MCP reource picker with component to list attached resources at the bottom of Chat Form
* - Model selector integration (router mode)
* - Loading state with stop button, disabled state for errors
*
* **Exported API:**
* - `focus()` - Focus the textarea programmatically
* - `resetTextareaHeight()` - Reset textarea to default height after submit
* - `openModelSelector()` - Open model selection dropdown
* - `checkModelSelected(): boolean` - Validate model selection, show error if none
*
* @example
* ```svelte
* <ChatForm
* bind:this={chatFormRef}

* - **Role-based rendering**: Different layouts for user, assistant, and system messages
* - **Streaming support**: Real-time display of assistant responses as they generate
* - **Agentic workflows**: Special rendering for tool calls and reasoning blocks
*
* The branching system uses `getMessageSiblings()` utility to compute sibling info
* for each message based on the full conversation tree stored in the database.
*
*/
/**
* **ChatMessages** - Message list container with branching support
*
* Container component that renders the list of messages in a conversation.
* Computes sibling information for each message to enable branch navigation.

* **Architecture:**
* - Fetches all conversation messages to compute sibling relationships
* - Filters system messages based on user config (`showSystemMessage`)
* - Delegates rendering to ChatMessage for each message
* - Propagates all message operations to chatStore via callbacks
*
* **Branching Logic:**
* - Uses `getMessageSiblings()` to find all messages with same parent
* - Computes `siblingInfo: { currentIndex, totalSiblings, siblingIds }`
* - Enables navigation between alternative message versions
*
* **Message Operations (delegated to chatStore):**
* - Edit with branching: Creates new message branch, preserves original
* - Edit with replacement: Modifies message in place
* - Regenerate: Creates new assistant response as sibling
* - Delete: Removes message and all descendants (cascade)
* - Continue: Appends to incomplete assistant message
*
* @example
* ```svelte
* <ChatMessages
* messages={activeMessages()}
* onUserAction={resetAutoScroll}

* - Handles action callbacks (copy, edit, delete, regenerate)
* - Displays branching controls when message has siblings
*
* **User Messages:**

* 4. Empty files detected and reported via DialogEmptyFileAlert
* 5. Valid files processed to ChatUploadedFile[] format
* 6. Unsupported files shown in error dialog with reasons
*
* **State Management:**
* - `isEmpty`: Shows centered welcome UI when no conversation active
* - `isCurrentConversationLoading`: Tracks generation state for current chat
* - `activeModelId`: Determines available modalities for file validation
* - `uploadedFiles`: Pending file attachments for next message
