The fold/inline/types passes and the jolt.passes façade were baked into neither
seed half and never invoked: compile-eval and build went analyze -> emit directly,
and `jolt build --opt` flipped an optimize flag that nothing consumed.
- Compile the passes into the image (emit-image manifest): fold, inline, types,
then the jolt.passes façade, after jolt.ir.
- compile-eval and build.ss now run jolt.passes/run-passes between analyze and
emit. Off the direct-link path it is a pure const-fold; `jolt build --opt`
turns on inline + flatten + scalar-replace + type inference (it sets
hc-optimize?, which inline-enabled? reads).
- The seed minter (emit-image) stays analyze -> emit, so the seed is built
un-optimized and the self-host fixpoint is unaffected.
build-smoke already exercised --opt; it now actually optimizes and still matches
the release binary's output. Corpus floor and the fixpoint are green.
