Make explicit that the loop may lean on Prolog backtracking (pl-query-all) and cut,
preferring clause-order precedence via pl-query-one. Default to sx_write_file over
path/pattern edits; flag that sx_insert_near drops all but the first form. Document
the loaded-env primitive restriction (includes?/chars/etc. undefined after prolog
preloads; use the tokenizer's surviving set) and that negation is the not(Goal)
functor, not the prefix \+ operator.
