adds self-hosted compiler is functionally: - The default compile path is the portable pipeline using jolt.analyzer (Clojure) → host-neutral IR → backend.janet. - The analyzer is itself Clojure, compiled by jolt for true self-hosting. - bootstrap-fixpoint passes (stage1 == stage2 == stage3): rebuilding the compiler on its own output. - clojure.core is now self-hosted in the overlay. - Stateful forms (defmacro/ns/deftype/defmulti/require/in-ns) are interpreted by design.
