Grzegorz MartensandClaude Opus 5.5 f5f139db28 M2.6: a page's content is read with its /DecodeParms given by reference ...

`decode_with_damage` and `decode_contents_with_damage` read a stream's
`/DecodeParms` only when direct, as `Stream::decoded` does, so content behind
a predictor whose parameters, or a number in them, are an indirect object
decoded with the predictor's tag bytes left in, and was taken as whole. Edit
then listed and wrote back the wrong bytes, and pruning dropped an image such
a form draws. ISO 32000-2 lets those values be indirect.

- `decode_with_damage` takes the document and reads the parameters through
  it, and so does `decode_contents_with_damage`, and `decode_contents` with
  it: printing, accessibility's reading of a page and a page copied as a form
  read them too. Code that calls `decode` on a stream itself doesn't yet.
- It reads through `Document::decoding_view`: `with_direct_parms`, but a copy
  of the stream holds only its `/Filter` and the parameters, its data shared,
  so a stream a page's `/Contents` lists again and again isn't copied whole
  for each.
