The repo mixed variants such as center/centre and color/colour, so a
name could be spelled either way and searches missed half the hits.
Standardize on the US spelling, matching .NET's own APIs (Color, Center).
Wire values owned by other systems keep their spelling: the material
ledger's "Cancelled" hold status and GitHub's "cancelled" job status.
No behavior change beyond the spelling of a few status messages.

MaximalRectangles.InRegion finds the largest axis-aligned rectangles that fit
wholly inside a Clipper region, such as a cutout shrunk by the part spacing.
It grids the region on its vertex coordinates plus even divisions, keeps a cell
only when no edge enters it and an even-odd row scan puts it inside, then runs
the shared histogram search.
Exact for regions with only horizontal and vertical edges; slanted and curved
edges are followed as a staircase that never crosses the boundary, short of the
true maximum by up to about one cell per side. Tests cover a rectangle, an
L shape, a frame with a hole, a round hole (inscribed square), a diamond and a
star; disabling the edge-crossing check fails the three slanted-edge tests.
The histogram search over a free/blocked cell grid never depended on the
obstacles being boxes. Move it to OpenNest.Core as MaximalRectangles.FromGrid
so other callers can build their own grids; RemnantFinder keeps building its
obstacle grid and calls it. No behavior change.
