Production fixes 1-7: detection bugs, cfar→threshold rename, digital gain control, Doppler mismatch protection, decimator watchdog, bypass_mode dead code removal, range-mode register (21/21 regression PASS)

Browse Source 
Fix 1: Combinational magnitude + non-sticky detection flag (tb: 23/23)
Fix 2: Rename all cfar_* signals to detect_*/threshold_* (honest naming)
Fix 3: New rx_gain_control.v between DDC and FFT, opcode 0x16 (tb: 33/33)
Fix 4: Clamp host_chirps_per_elev to DOPPLER_FFT_SIZE, error flag (E2E: 54/54)
Fix 5: Decimator watchdog timeout, 256-cycle limit (tb: 63/63)
Fix 6: Remove bypass_mode dead code from ddc_400m.v (DDC tb: 21/21)
Fix 7: Range-mode register 0x20 with status readback (USB tb: 77/77)
