Clarify that outputDrive controls only the composite signal path while PlutoSDR hardware gain stays fixed at 0 dB. Relax outputDrive validation to allow stronger composite drive during hardware tuning and update the Pluto example config accordingly.
Introduce CLI TX mode, hardware driver selection, IQ resampling to device rate, and platform-specific PlutoSDR/SoapySDR integrations. Update engine pacing for blocking hardware writes and refresh docs/release notes for the hardware-ready v0.6.0-pre milestone.
