- Add sexp_to_jax.py: JAX compiler for S-expression effects
- Use jax.random.fold_in for deterministic but varying random per frame
- Pass seed from recipe config through to JAX effects
- Fix NVENC detection to do actual encode test
- Add set_random_seed for deterministic Python random
The fold_in approach allows frame_num to be traced (not static)
while still producing different random patterns per frame,
fixing the interference pattern issue.
