feat: complete Task #4 - Tauri backend commands working

Task #4 COMPLETE (95% project completion):
- ✅ All 3 Tauri backend commands functional
  - validate_inference (Anti-Crash validation)
  - get_vexation_index (operator stress metrics)
  - submit_feedback (Feedback-O-Tron submission)
- ✅ ReScript bindings working via @tauri-apps/api
- ✅ TEA command wrappers integrated (TauriCmd.res)
- ✅ All 33 tests passing (719ms)
- ✅ Build successful (180ms)

Architecture:
- Using direct @tauri-apps/api FFI (proven, stable)
- rescript-tauri prepared for future migration (built, symlinked)
- Added rescript-tauri to bs-dependencies

Next: v0.1.0 release preparation (5% remaining)
