Matiq 2eb3b690c9 Add bit-exact RFFT infrastructure from decompilation (th1a90/th2180) 
- fft.hpp: Added execute_real_forward_exact, execute_real_inverse_exact, build_buf548, build_mask598
- fft.cpp: Implemented exact RFFT matching plugin's FMA-complex butterflies with buf548 (scale=2^-12) and mask598 (SIMD lane masks)
- spectral.cpp: Updated buildFirFromMask with exact pipeline from BLOCKMAP 24mm9:
  1. design = ln(mask) → negate
  2. opA = inv-RFFT (th2180)
  3. fold: DIVIDE FIR[1..2047], zero FIR[2049..4095]
  4. opB = fwd-RFFT (th1a90)
  5. EXP: complex polynomial exp with q≈0.80
  6. opC = inv-RFFT (th2180)
  7. window: falling Hann WIN_freq[2048..4095]
  8. opD = fwd-RFFT (th1a90)
  9. normalize: FIR[0]=1.0, FIR[1]=0.0

Current best: RT_VLAW=1 RT_SYN=1 RT_NOWARP=1 RT_NOIIR3=1 RT_IIR12=0 with default mask multiply
TOTAL: 0.750 dB (vs 1.594 bridge)

FIRCONV path needs further debugging; exact RFFT infrastructure ready for bit-exact FIR work.
