* fix(cursor): hydrate SelectedImage via blobIdWithData + JPEG soft-cap
Cursor vision expects SelectedImage.blob_id_with_data (field 9) backed by
the session blobStore, and large clipboard PNGs need JPEG soft-cap prep
rather than a hard 1 MiB reject before encode.
* docs(changelog): add fragment for Cursor SelectedImage blobIdWithData fix
* refactor(cursor): split image protobuf encoding
