Expand Spacing opens up a whole selection; nests that are a hair short
of fitting need the opposite: move only the parts the overlap check
flags, by the shortfall, and leave everything else where it is.
Fix Spacing pushes one part of each flagged pair straight away from the
other and ripples the push into neighbors it crowds, so rows already
locked in at the spacing can make room. When a plate is packed edge to
edge and no straight push fits, a constraint relaxation shares each
shortfall between both parts along the closest-point normal. Every
result is confirmed by the overlap check before any part moves, and is
applied only when it has fewer findings and nothing new.
NativeContours gains a coarse-flattening overload, Translated, Nested
and a closest-points GapTo for the search.

A single-drawing selection that fits no one lattice, such as staggered rows
topped by straight ones, now counts as a pattern when its rows share one
pitch along X (or Y). Each row stretches rigidly instead of the selection
falling back to the slow pair search.

A selection that repeats on a lattice (a fill) now has its lattice scaled
along X, then Y, as far as the work area and clearance floors allow, so the
pattern survives. Multi-part motifs stay rigid, no selected gap closes below
the smallest entry gap, and parts never pass through fixed material. Other
selections keep the pair search.

Expand Spacing measured every ring pair of every part pair for each trial
move, so a packed layout of parts with holes took minutes per spacing
probe. Skip ring pairs, far part pairs and off-path parts whose bounds
already settle the answer.
Every pair was also held at its full starting gap, so parts could not
move toward anything and most layouts stayed at their entry spacing.
Part pairs may now close to the spacing being tried, never below a
smaller starting gap. Cut-offs and clamps keep their full entry gap.

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.

Remove a private part reference from the lead-in notes, fix the Options and
New menu paths, say that release ZIPs never auto-update, describe current
Cincinnati CL ordering, clamp validation coverage and empty-plate saving,
list every built-in engine, and drop internal decision labels.
Expand now reads the plate on a worker while its Cancel window pumps
messages, so a still-running fill could commit parts into the plate the
search is enumerating (InvalidOperationException: collection modified).
Refuse the command while whole-job nesting, a NestProgressForm or a fill
on any view of the nest is active. The usual plate-action guard is not
reused: ActionSelect reports busy whenever parts are selected, which
Expand requires.
