Research direction
Reproduce the crash with jac2cheb([1.0], 0, 0) on the reported M1/Rosetta setup. Start at src/libfasttransforms.jl:400 and src/libfasttransforms.jl:515, where the stack trace enters plan_jac2cheb; investigate the illegal instruction from libfasttransforms.dylib. Done means the same call no longer crashes on the reported system.
