By the user's decision, recipe packages are open again: the card's
export button and the detail's More menu make a .zip named after the
recipe (workflow, notes, tags, parameters, cover, model thumbnails;
versions only when ticked). Dropping one into the Workflows page's
share and import dialog inspects it and keeps it as a new recipe card,
optionally opened on the canvas.
An import never replaces a recipe any more: the "replace" path, which
erased the old recipe for good, is gone; a taken name gets " (2)".
Assets and versions move in before the recipe file, and a failure
removes only this import's new folders. The release gates and their
503 answers are removed. Tests: new card and renaming, nothing left
after a failed import, tampered and escaping packages refused.
