Grain Summary
Compute aggregate statistics for all grains in a mask: count, density, coverage fraction, mean/median area, total volume, and height statistics. Equivalent to Gwyddion's grain_summary.c module.

Notes
- Reported statistics: grain count, grain density (count per unit area), coverage fraction, mean area, median area, total volume, mean height, median height, max area, min area.
- Volume is computed relative to the mean height of the non-grain background.
- Use Grain Analysis for per-grain statistics, or Grain Distributions for histograms.
