Port the java.lang.String/CharSequence method surface to the Chez RT so (.toUpperCase s), (.substring s a b), (.indexOf s x), the regex methods (.matches/.replaceAll/.replaceFirst/.split), etc. run on a string target. natives-str.ss holds jolt-string-method, ported from the seed's surface in eval_resolve.janet: ASCII case mapping (byte-oriented like the seed), -1 on indexOf miss, flonum numeric returns to match jolt's number model, Scheme chars for charAt, and the regex methods over the irregex compiled via jolt-re-pattern. record-method-dispatch gains a string? arm that falls through to it (unsupported methods still throw). Corpus prelude floor 2002 -> 2026 (+24), 0 new divergences. _str 27/27 vs build/jolt; full jpm test + conformance x3 green. The (. x m) dot-form (the . special form, distinct from .method sugar) and the clojure.string namespace (needs prelude plumbing + Pattern) stay deferred.
