The importer skipped a slide whose part was missing or unreadable and only
logged it, so `info` showed one slide fewer with exit code 0 and a save wrote
the shorter deck over the original.
`deckcraft_pptx::import_checked` returns the parts it left out (`import` is
unchanged). The engine carries them as `Damage::slides` next to the damaged
media of a `.deckcraft` file: `file.open` and `file.openBytes` return
`lostSlides`, the app shows a message and opens a repaired copy (so Save asks
for a new name), and `deckcraft-cli` warns on stderr.

An object DeckCraft doesn't model kept its XML, but the parts that XML
points to (diagram data, layout, style and colours; an OLE embedding)
were not kept, so a save wrote it as an empty rectangle or its preview.
Opaque now carries those parts (relationship id, full relationship type,
the part as a media item) and the writer re-adds them under the slide's
new relationship ids. A part with relationships of its own, or an
external link, still falls back to the preview with the existing
warning. A diagram's data part loses its link to the cached drawing,
which is a slide relationship id a save renumbers; only diagrams whose
drawing is missing or empty reach this path.
