Replace FT601Connection with FT2232HConnection in radar_dashboard.py and
smoke_test.py. Both files had broken imports after FT601Connection was
removed from radar_protocol.py. Also update requirements_dashboard.txt
(ftd3xx -> pyftdi) and GUI_versions.txt descriptions.
Align test suite with FT601 removal from radar_protocol.py:
- Replace FT601Connection with FT2232HConnection throughout
- Rewrite _make_data_packet() to build 11-byte packets (was 35-byte)
- Update data packet roundtrip test for 11-byte format
- Fix truncation test threshold (20 -> 6 bytes, since packets are 11)
- Update ReplayConnection frame_len assertions (35 -> 11 per packet)
57 passed, 1 skipped (h5py), 0 failed.
- radar_system_top.v: DC notch now masks to dop_bin[3:0] per sub-frame so both sub-frames get their DC zeroed correctly; rename DOPPLER_FFT_SIZE → DOPPLER_FRAME_CHIRPS to avoid confusion with the per-FFT size (now 16)
- radar_dashboard.py: remove fftshift (crosses sub-frame boundary), display raw Doppler bins, remove dead velocity constants
- golden_reference.py: model dual 16-pt FFT with per-sub-frame Hamming window, update DC notch and CFAR to match RTL
- fv_doppler_processor.sby: reference xfft_16.v / fft_twiddle_16.mem, raise BMC depth to 512 and cover to 1024
- fv_radar_mode_controller.sby: raise cover depth to 600
- fv_radar_mode_controller.v: pin cfg_* to reduced constants (documented as single-config proof), fix Property 5 mode guard, strengthen Cover 1
- STALE_NOTICE.md: document that real-data hex files are stale and need regeneration with external dataset
