jolt/host/chez/cli.ss
Yogthos 7e2704642b deps.edn resolution + a file loader + a project-aware CLI
joltc grew from a single -e expression into a real project runner. require now
loads a namespace's .clj/.cljc from the source roots transitively (load-once),
so a multi-file project works; the corpus/unit gates load compile-eval.ss but
not the loader, so their alias-only require is unchanged.

jolt.deps resolves a deps.edn into ordered source roots — git + local deps only
(no Maven), breadth-first so a top-level pin wins, with aliases (:extra-paths/
:extra-deps/:main-opts) and tasks. Git deps clone into a sha-immutable cache
($JOLT_GITLIBS, else ~/.jolt/gitlibs) by shelling out to git via a new
jolt.host/sh primitive. jolt.main dispatches run -m / -M:alias / -A / repl /
path / a deps.edn task. The launcher passes the user's cwd as JOLT_PWD (the
project dir) since it cd's to the repo root for the runtime's relative loads.
