elp(realizer): close subordinate-clause round-trip + silent-e/doubling lemmatizer + verb-final object bug + ES/PT closed-class verb guard

- realizer now carries the subordinate clause verbatim (subord_text slot): the
  5th English acceptance sentence is byte-identical through parse->realize->reparse.
- English -ed/-ing lemmatizer restores silent-e (loved->love) and collapses
  inflectional doubling (stopped->stop), inverting en_verb_past().
- parse_spec_lang: a sentence-final main verb no longer bleeds into the object
  slot (cstart advanced to verb+1), so intransitives round-trip.
- cp_rom_is_verb rejects closed-class words (prep/det/pron/aux/neg) before the
  ending-only test, killing the 'para'/determiner misfires.

EN telephone gate 5/5 (now byte-identical 5/5), Romance gate 6/6.
