Claude 275037932f Gap 19: ODT embedded spreadsheets and OLE objects kept whole ...

LibreOffice writes an embedded object's replacement picture in its own
metafile format, which WordCraft can't decode. So an embedded
spreadsheet (`draw:object`, ODF 1.3 §10.4.6) or OLE object
(`draw:object-ole`, §10.4.7) vanished on open, and saving lost it.

Such objects are now kept whole: their files, media type (from the
manifest or the sub-document's body) and replacement picture.
- Display: the replacement picture when WordCraft can show it, else a
  placeholder of the object's size drawn in code (ruled for a
  spreadsheet).
- ODT save: written back as the same object, with its manifest entries
  and original replacement. LibreOffice renders a round-tripped
  spreadsheet pixel-identically.
- Document model: the files live in `passthrough` under `odf-object/`,
  linked from the picture's `ole` by a marker. The DOCX writer skips
  the marker and writes the picture alone.

Flat ODT, a fix to the chart commit: inline sub-documents lacked the
required `office:mimetype`, so the schema rejected flat files holding
charts. Sub-documents now go inline as full `office:document`s (media
type, styles, settings) and are split back into their files on
opening. Replacement pictures and OLE files go inline as base64. A
picture's data is matched to the element that holds it, no longer to
the last `draw:image` before it.

Cargo.toml

#3692: review — pasted text boxes skip only the box over the budget, and say so; media_index private; kept markers' order pinned
