Matiq a1632a9fce fix: persistent IIR state eliminates ×1.805/×2.44 gaps 
Root cause: IIR accumulator reset to 0 every frame, losing temporal state.
Fix: static thread_local accumulator persists across frames.

Results (dual_b1q_0.5, reaper render):
  cut@500 = -10.32 dB (EXACT match, was -14.35)
  cut@2000 = -11.82 dB (EXACT match, was -6.58)

Both the ×1.805 (OLA normalization) and ×2.44 (mask computation) gaps
were caused by the same root issue: IIR state reset.

22w: faithful mask-shaping chain v1 behind RT_FAITHFUL (fnfaith.cpp) — exact 180533340 freq-warped bidir-IIR coefficients (fc_bin=85@48k/4096, constants from dump); corpus TOTAL 5.315 but comb 2.57 best-ever; decisive: mask shape cannot balance dual tones -> level contrast is created by the DETECTOR (time-domain twin bank hypothesis priority #1)
