FillEndOdd and FillEndEven had no production callers, so round parts
only got stripe layouts. A Circle strategy now runs them in the fill
pipeline: 8in circles on a 60x120 go from 98 to 112.

FillStrategyRegistry now holds a fixed, ordered list of the seven
built-in strategies (Pairs, Row, Column, RectBestFit, Extents, Linear,
TiltedRemnant, in their Order sequence) instead of reflecting over the
Engine assembly. LoadFrom and LoadPlugins are gone; nothing outside
tests called them, so outside IFillStrategy plug-ins were never loaded
by a shipped host and none are loaded now. IFillStrategy stays public.
The disabled set stays process-wide and keeps its Disable, Enable,
SetEnabled, Strategies, AllStrategies and DisabledNames behavior for the
Options form. DefaultPlateFiller still reads Strategies, so interactive
Fill, the fixed-strategy engines, Irregular's block catalog and private
plate fill, the cutout lattice fill and the brute-force runner all keep
honoring it.
PlateViewFillLifetimeTests drives fills through PlateView, which builds
its own filler, so a filler-level seam can't reach it. The registry gets
an internal UseForTesting hook that swaps the list until disposed, and
the WinForms test project can see Engine internals for it.

Fill only tried 0 and 90 degrees for parts classified as rectangles, so a long
part filling a 60 x 120 plate four high at 90 degrees left a 55 x 59 strip empty
although two more fit tilted about 33 degrees (a reported nest: 4 placed, 6 fit).
The second tilted part only fits with its corner tucked beside the grid, in the
strip the grid's slack leaves, so a plain rectangular remnant fill finds one.
TiltedRemnant runs after the other strategies. It moves the best layout flush to
one end so leftover room becomes one remnant, and to either end of the other axis
so its slack forms one strip; then tiles the part at the most upright angles that
fit the remnant's height and keeps only copies at least the part spacing from the
layout. It is skipped when the part fits the remnant upright, for circles, for an
explicit rotation range and once the requested quantity is placed.
Fill benchmark (--parallel 1): the synthetic set is unchanged (all valid, same
cost and plates). The reported part needs 1 sheet instead of 2 for 6 parts and
2 instead of 3 for 12.

Repo-wide sweep with the pinned CSharpier 1.3.0 tool. Whitespace and
line-wrapping only; OpenNest.Engine.Tests (109) and OpenNest.IO.Tests
pass after reformat, full solution builds 0 errors.
Added .csharpierignore so csproj/config XML keeps its existing layout
(CSharpier's XML wrapping churns attributes with zero benefit).
Formatting is now enforceable: dotnet csharpier check . passes.
Move fill algorithms to OpenNest.Engine.Fill namespace:
FillLinear, FillExtents, PairFiller, ShrinkFiller, Compactor,
RemnantFiller, RemnantFinder, FillScore, Pattern, PatternTiler,
PartBoundary, RotationAnalysis, AngleCandidateBuilder, and
AccumulatingProgress.
Move strategy layer to OpenNest.Engine.Strategies namespace:
IFillStrategy, FillContext, FillStrategyRegistry, FillHelpers,
and all built-in strategy implementations.
Add using directives to all consuming files across Engine, UI,
MCP, and Tests projects.
