compiler: text keys below a row, trf padding and tr's cast (ECS's 26.4 gaps) - a @Text Key in a record nested in a row, or in each item of a list of them, is filled with its derived key <registry>.<row>.<field>.<i>.<field> as a top-level one is, and a @Text []Key a row leaves out takes <...>.0, .1, ... for as many as en.po has (so no .lres spells a key; the manifest and en.po are now read before the parse that fills the rows); field: null is no text; trf / trn's trailing "" literals are padding, not counted against the English's holes; and string(x) of a string or a Key is x itself to the escape analysis, no allocation site, so tr(key) passes arena strict (a template's lone hole still copies); examples/lang/i18n_nested and its feat_case (added, not run); LANGUAGE.md and the changeset; reseeded, bootstrap-cfree fixpoint holds
