eval-toplevel now routes every compiled form through backend/compile-and-eval
(analyzer -> IR -> Janet back end). The bootstrap compiler (compile-ast) stays
only to bootstrap jolt.ir/jolt.analyzer in backend/compile-load. Dropped the
:selfhost? flag and JOLT_SELFHOST env plumbing — self-host is the default.
Three correctness fixes the full-suite-under-self-host sweep exposed:
- analyzer/back end: recur into a variadic arity now compiles. The arity fn
gets an ordinary positional rest param (the collected seq), with a dispatch
wrapper, so (recur fixed... rest-seq) is a clean self-call like Clojure --
instead of punting to the interpreter, which hangs on this (jolt-4df).
- host_iface: interop heads (.foo/.-field/Foo.) and ns-management forms
(all-ns, create-ns, resolve, ...) now mark uncompilable so they fall back
instead of compiling to a bad call.
- back end: named-fn self-reference ((fn self [n] ... (self ...))) binds the
fn name via a var.
Full unit+integration suite green; clojure-test-suite battery holds 3913.
