jolt's `is` was a fixed macro with no assert-expr multimethod, and the runner bypassed the report multimethod, so libraries couldn't register custom assertions or custom report types (e.g. test.check's ::trial/::shrunk). Add assert-expr (2-arg [msg form], dispatch on the form's first symbol / :default / :always-fail), do-report routing through report, and report :pass/:fail/:error methods that feed the counters. `is` dispatches to an explicitly-registered assert-expr method before its inline path, so thrown?/ thrown-with-msg?/= and every built-in form stay byte-identical. Runtime stdlib only, no re-mint. test/chez/clojure-test.clj self-checks the extension points + full is/are/testing/thrown?/use-fixtures surface; smoke gate runs it.
