Yogthos 1d345bfd0f jolt build: bundle native libs + resources into standalone binaries
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.
