 * Issue #627: image-to-pdf-group presets (jpg-to-pdf, png-to-pdf, ...) combine
 * every uploaded file into one PDF via their own multi-file route, the same
 * as the base image-to-pdf tool. They must stay off the generic per-file
 * batch path, which never registers them (registerImageToPdfRoute bypasses
 * the createToolRoute/registerToolProcessFn registry the batch route depends
 * on) and 404s with `Tool "<id>" not found` if reached with 2+ files.
