feat(attachments): data layer for task file attachments

TaskAttachmentEntity (+config, cascade FK), TaskAttachmentRepository, and an AttachmentStore that writes files under ~/.todo-app/attachments/<taskId>/ with a path-traversal guard and a 5 MB cap. TaskPromptComposer gains an optional read-only 'Reference files' section. Migration AddTaskAttachments.
