Six-decimal incremental PEP programs round arc centers, so an arc's end
tangent misses its neighbor's by about gap / radius (1.6e-5 rad on the
offset 5/32" fillet in the reported nest). Two parts resting one spacing
apart then gave the slide contact a Minkowski cone a hair wider than a
half-plane, which the classifier read as the whole plane: every direction
blocked, so the top part could not be pushed sideways along the part below.
SlideContact now reads a cone up to TangentSlack (1e-4 rad) past a
half-plane as a noisy half-plane and widens its boundary and concave-ray
comparisons by the excess, so near-tangential slides read as tangential.
A direction admitted that way can enter material by at most travel x
excess at that contact, and every other contact is still classified on its
own; wider cones remain real overlap and block. Raising JointTolerance was
not needed for this case and is left at 1e-6.
Whole-job benchmarks (synthetic nests plus the PEP job at 3 and 60 parts,
--parallel 1) are identical before and after for every engine.

Share the nest server client setup and page validation, entity endpoints,
post marker checks and the repeated desktop list, cut-time and busy-warning
code. Persistence tests use NestArchiveJson. No behavior change intended.

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.

PEP-rounded drawings can leave a contour 1e-6 short of closing. ShapeBuilder
chains it as a loop at Tolerance.ChainTolerance, but the slide classifier
re-recovered loops at 1e-7, so the whole part became unresolved and every
contact with it blocked. Parts placed in its cutout at exactly the part
spacing could not be pushed (Y/X keys) in any direction, even away from the
wall. Recover loops with the same tolerance ShapeBuilder uses.

Drawing data can fix a fillet's center slightly off the tangent normal, so
the arc's end sits ~1e-7 past its neighbouring line's end. The slide contact
classifier only joined entities within 1e-7, so a contact at that tangent
point read as two boundaries, was classified ambiguous and blocked the push.
In N26-243 this stopped a part pushed left along another once the parts
aligned. Contacts within 1e-6 of a joint now take the joint's tangents;
the 1e-7 incidence tolerance is unchanged.
