Account for jolt's layered interop surface on Chez — the janet.* bridge, the
FFI-backed java.* shim libs (http-client TLS/gzip, router, db), jpm-module Janet
deps (spork/http) — with ../examples as the end-to-end acceptance gate. New
epic child jolt-cf1q.7, gated behind Phase 2.
Phased plan for re-hosting jolt's substrate on Chez Scheme, organized around two
north stars: minimal host shim (push everything possible into self-hosted
jolt-core, drop the tree-walking interpreter) and the spec/conformance corpus as
the host-neutral correctness contract. Closes obsolete Janet-backend/cgen beads
superseded by the native substrate.
