fix(fft): replace iterative twiddle with direct cosf/sinf, add tests A-E
fft_radix2 now computes wr=cosf(angle*k)/wi=sinf(angle*k) directly per k,
eliminating float drift over long iteration runs. Iterative approach
documented in comment for reference. Tests A-E added (bit-reverse, small-N
DFT, twiddle drift, DCT small/large N). arrays_match tolerance reverted to
5e-3. TODO.md updated.
handoff(Gemini): fft twiddle fix complete, 38/38 tests passing.
