Detailed Description

No-embed (subprocess) default fringe plotter. Implements the same MHO_FringePlotVisitor interface as the embedded MHO_DefaultPythonPlotVisitor, but renders by shelling out to the user's python3 (python -m hops_visualization.fourfit_plot <request.json>), passing the plot data as JSON. No libpython is linked.

Author: J. Barrett - barre.nosp@m.ttj@.nosp@m.mit.e.nosp@m.du

The C++ side already holds the plot data as mho_json (MHO_FringeData:: GetPlotData()), and the Python renderer (make_fourfit_plot) is entirely dict-driven, so the subprocess path produces the same plot as the embedded path for the DEFAULT plotter.

Scope / behavior (decided):

DEFAULT plot only. Custom Python plots (/control/config/python_custom_plot) are NOT supported here; if requested we warn and render the default plot.
On any failure (no python3, import error, render error) we WARN and SKIP the plot, then continue processing. No hard error, no matplot++ fallback.
