Stop normalizing documentation text in the diff tool

Match the exporter: documentation text is exported as authored, so the
diff tool has nothing to reconcile in descriptions, tag content, or the
`refers`/`link` tokens — and normalizing them would hide a real change
in exactly the fields the exporter promises not to touch. Expression
and type fields keep the anchored-prefix normalization the exporter
still applies.
