Needed by #23833 Adds a `chat_file_links` association table to track which files are associated with each chat. - `AppendChatFileIDs` query links a file to a chat with deduplication - `GetChatFileMetadataByIDs` query returns lightweight file metadata by IDs - Tool-created files (e.g. `propose_plan`) are linked to the chat after insert - User-uploaded files are linked to the chat when the referencing message is sent - Single-chat GET endpoint hydrates `files: ChatFileMetadata[]` on the response > 🤖 Created by Coder Agents and massaged into shape by a human.
