Initial commit: soothe2 RE workspace + roadmap

- Инфраструктура: RTTI-дампы (rtti_dsp/full.json), декомпиляции DSP-классов (decomp_*.txt),
  Ghidra-скрипты (Dump*.java, ImportRtti*.java, Diag.java), depthcurve/curve_fits LUT.
- Поведенческая модель sim_v5.py + sim.py (RMSE ~0.3dB), утилиты (measure, tt_sweep, patchparam,
  sweep, harness_*, verify_sim).
- summary.md + roadmap.md (контракт из manual M1-M12, топология пайплайна из OCR, фазы A-C).
- pipeline_ocr.txt: OCR диаграммы Appendix A (mid/side ручка, trim/mix/bypass порядок).
