- 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.

# but the shader path is the one this PR's bounding pipeline targets).
