A built binary dropped its deps.edn :jolt/native declarations and its
resource roots, so an FFI+resources app (ring-app) failed at runtime:
sockets/sqlite gave 'no entry for socket' and io/resource returned nil.
The buildsmoke fixture is pure compute, so neither path was exercised.
The launcher now loads required + :process native libs before the app's
top-level forms (a library's defcfn resolves its foreign-procedure symbols
at top-level eval during startup, so the libs must be loaded first);
optional libs load in the scheme-start launcher, where a missing lib is
caught rather than aborting the heap build.
deps.edn :jolt/build {:embed [dirs]} bakes those dirs' files into the heap
(register-embedded-resource! at heap build), so io/resource serves them with
no files on disk. Non-embedded resources resolve at runtime against JOLT_PWD,
and io/file reads (e.g. config.edn) stay external.
build-binary now takes the encoded natives, embed dirs, and project paths
from cmd-build; deps/resolve-project surfaces them. Buildsmoke fixture grows
an embedded resource + a :process native to cover both paths.
Restores the standalone-binary capability the Janet host had. `bin/joltc build
-m NS -o OUT` AOT-compiles an app into a single self-contained executable — the
whole runtime, clojure.core, stdlib and compiler embedded, no Chez install or
jolt source needed at runtime.
Pipeline (host/chez/build.ss, host primitive jolt.host/build-binary driven by
jolt.main's build command): resolve deps, load the entry namespace recording the
app namespaces in dependency order, re-emit each to Scheme, textually inline the
cli.ss runtime load sequence into one flat source + the app + a launcher, then
compile-file -> make-boot-file -> embed the boot as C bytes -> cc-link against
libkernel.a.
Two non-obvious bits: the compile pass runs in a fresh Chez, not the loaded
runtime (regex.ss shadows top-level `error`, which otherwise bakes a broken
reference into the boot); and the launcher installs scheme-start rather than
running -main at top level, since boot top-level forms execute during heap build
before argv is set, so args only reach -main through scheme-start.
Loader: a require of an in-memory namespace with no source file now no-ops, so
AOT'd app namespaces satisfy require in a built binary.
Mode flags (--opt/--dev, default release) are plumbed; the optimization passes
they gate come in a later stage. RFC 0007 has the design. Gated by `make
buildsmoke`.
