Trying to clean up these horribly ugly old proofs, but the requirement of constructivity makes it very difficult

prefer rewrite_term_yoyo for improved performance and occasionally better results (conforming to Ast.normalize);

revert b35c2aa05fcf: redundant due to 89ea66c2045b, if object-logic judgment lacks delimiters;

clarified position constraints: omit redundant information, e.g. for implicit object-logic judgment;

unused (see 0199acc01aa8);

notable performance tuning (amending a59d9b81be24 and 8976c5bc9e97): avoid costly could_beta_eta_contract, which traverses the whole term; always use Item_Net.retrieve instead, but on frozen TVars/Vars to enforce matching instead of unification;
