Test model

$ harbor run -p tasks/fft_rust \
  -a claude-code -m claude-opus-4-6

Description

Implement a fast Fourier transform in Rust to compute the DFT of a length-32768 real signal as quickly as possible. The input length is always a power of two, and correctness is verified via Parseval's theorem and spectral checksum. Only the Rust standard library may be used.
