- Move WaveformConfig() from per-frame local in _run_host_dsp to
self._waveform in __init__, mirroring ReplayWorker pattern.
- Add set_waveform() to RadarDataWorker for injection symmetry with
ReplayWorker.set_waveform() — live path is now configurable.
- Replace hardcoded fallback 32 with self._waveform.n_doppler_bins.
- Update AST contract tests: WaveformConfig() check moves to __init__
parse; attribute chains updated from ("wf", ...) to
("self", "_waveform", ...) to match renamed accessor.
