CopyEntityBatchQuery::new looked up source columns via Table::column, which deliberately hides tsvector (fulltext) columns. Because fulltext columns are nullable, they were silently dropped from the copy instead of hitting the non-nullable error path, so the destination's fulltext search column and its GIN index were left empty after a copy/graft. Add Table::column_including_fulltext and use it in the copy so fulltext columns are matched and their already-computed tsvector value is copied verbatim; document that Table::column skips fulltext search columns. Add a regression test that copies the User table and verifies a fulltext query against the copy returns the expected entity.

Should can_copy_from also use column_including_fulltext it uses column() currently?

One thing that claude flagged during the review:
is_assignable_fromonly compares FulltextConfig, which is language and algorithm, not fulltext_fields. So a graft that adds a field to include: copies the old tsvectors and searches on the new field quietly return nothing. Comparefulltext_fieldshere too?
