Sky Johnson d541c1eda8 Replace naive O(N²) IMDCT with FFT-based O(N log N) implementation 
Port stb_vorbis's optimized inverse MDCT algorithm: pre-twiddle with A
factors, iterative butterfly passes (radix-4/radix-2), bit-reversal
permutation, post-twiddle with C and B factors. Twiddle factors are
precomputed with f64 precision at init time.

Performance: 703x realtime (75s audio decoded in 0.107s) vs the naive
approach which was too slow for real-time playback, causing buffer
underruns and audible gaps. Accuracy matches stb_vorbis output.
