Open saved figures via xdg-open/open/startfile when no GUI backend
exists, and extend the potential map's color range below the V- mean
reference instead of clipping it.

- Refuse the uniform contact model when the fills form multiple
disconnected copper groups that each touch both terminals: the
prescribed injection split is ill-posed and the grounded system was
singular, silently returning garbage (e.g. negative gigaohms).
connected_restrict now reports the component count; a power-balance
backstop (SolverError) catches any other inconsistent solve.
- Connect via/pad barrels to the nearest fill copper within the pad
footprint (+1 cell) instead of only the exact center cell, so
thermal-relief spokes still stitch layers; barrels that reach fill on
fewer than two layers are warned about. ViaLink gains pad_nm
(extracted from the padstack, JSON-roundtripped).
- Validate dialog input on OK (layers, current > 0, cell > 0, parseable
frequency, extra Cu >= 0) with an inline error instead of silently
substituting defaults; parse_frequency raises on garbage; pipeline
rejects i_test <= 0; choose_cell_size rejects non-positive overrides.
- Warn when a contact part is dropped by the connectivity restriction;
floor instead of truncate in cell_of; correct the uniform-model
summary line; drop an unused variable; refresh plugin.json wording.
