An unknown reader tag produced the reader's internal form
{:jolt/type :jolt/tagged :tag :#foo :form bar}, which tagged-literal? didn't
recognize and which leaked as a raw map when printed:
(tagged-literal? (read-string "#foo bar")) => false ; want true
(pr-str (quote [#foo bar])) => "[{:jolt/type :jolt/tagged ...}]"
Both the data path (rdr-construct-tag) and the compile path (emit-quoted) now
build a real tagged-literal for a tag with no registered reader, like Clojure's
*default-data-reader-fn*, so tagged-literal? / :tag / :form / printing all work.
clojure.edn reads raw forms through a separate __read-form-raw path and applies
:readers/:default itself, so it is unaffected.
Re-mint (backend + reader are seed sources); prelude byte-identical, image only.
make test green (selfhost holds, 0 new/stale), +2 unit rows.
