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

Browse Source 
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.

## Requirements
- Linux (POSIX shared memory; GPIO on Raspberry Pi).
- Linux (POSIX shared memory; GPIO on Raspberry Pi). The deployment target is a
**Raspberry Pi 5**; hardware PWM gating for the generator sweep is Pi 5
specific (GPIO12/13/18/19, `dtoverlay=pwm-2chan`).
- A C++20 compiler and `make` — Eigen and nlohmann/json are vendored, so no extra C++ dependencies are needed.
- Python 3.12 with a virtual environment.
- **Python 3.10 or newer**, in a virtual environment.
