- Renamed grid terminology and command/API surface from `inf`/“infinite” to `gpu`/“GPU”, plus `viewAdaptive` for camera-relative sizing. - Updated OpenGl grid rendering to compute adaptive bounds from the visible region and to fix axis coloring for rotated rectangular grids. - Refreshed Draw tests, help text, and API comments to match the new behavior.

# -viewAdaptive derives both the cell size and the rendered bounds from
|
|
# the visible region (camera scale + viewport unprojection). Zooming in
|
|
# should keep cells visible and roughly the same screen-space density;
|
|
# zooming out should adapt the rendered extents to enclose the new view.
