Scope whole-program optimization to app namespaces (jolt-87e) (#126)
Under JOLT_OPTIMIZE a -m program run inferred + specialized EVERY loaded
namespace, including every transitive dependency. On a dep-heavy app that's
prohibitive: malli-app cold-started in ~2m10s (hundreds of dep namespaces, each
run through the per-form inline + inference passes).

The closed world a whole-program pass reasons over is the APP, not its
libraries. jolt-deps now passes the project's own source roots (its deps.edn
:paths) to the runtime as JOLT_APP_PATHS. A namespace loaded from an app root
gets full optimization (and joins the one whole-program fixpoint); a dependency
namespace compiles at default cost — :inline? off for its load, so the per-form
optimize passes don't run over library code — staying direct-linked but
generically typed (the open-world default). With no app roots declared (a bare
program run, or jolt without jolt-deps) everything counts as app, so behavior is
unchanged.

malli-app JOLT_OPTIMIZE cold start: 2m10s -> 4.5s. Compute-heavy programs whose
hot code is their own namespaces (the typed ray tracer) are unaffected — their
code is app code and still fully optimized (9s/frame render). Applied at runtime
in main for the same baked-at-build-time reason as JOLT_PATH; added to the
ctx-image cache key. Help text corrected: optimization is opt-in, not default.
