A Soul pass found the two sides compile against different stdlib text:
the wasm bundle's si.smooth stalls in float32, the sandbox's faustlibraries
master does not. Reword the report, README and render.js; fail on length
mismatch and render errors; check output count; match controls exactly;
default output under the temp dir.

Add FaustNativeRender and native-diff.mjs; render thruster, two sfxr
patches and a tract vowel through both and record the numbers.
