per-point switching: hardware bring-up, profiles, protocol doc

Verified on the bench that the modified master bitstream excites in every stage
and the RF switch routes: 16 traces per sweep, 62 dB between the two switch
positions of one master port, 9.9k measurements/s. Adds the built master image,
two run profiles, a verification script and librevna_protocol.md, and drops the
stale prototype driver copy that the firmware tree still carried.

+The sources started as a verbatim import of the original standalone tool, but are
+**no longer identical to it**: the collector now drives the RF switches itself
+(switch-aware mode, `SwitchSequencer`), stepping to the next combination inside
+the hardware idle gap between sweeps and flagging a sweep *dirty* when a readout
+backlog means the toggle could not have landed in that gap. It therefore reuses
+the orchestrator's switch drivers and the shared `run_config` loader, which is why
+its build has its own include set and its own `build/kamil/` object tree.

+The wire format towards the Python producer is unchanged.
