Quality review of 50884da found the unshown RichTextBox oracle compared
cached CRLF text against the highlighted editor's native LF-normalized
text, which would fail on first Windows execution. Compare generated
text with normalized line endings on both sides instead, capture the
status label and preview state inside the ProgramChanged handler to
prove fallback-before-notify ordering, document the HighlightSpan
UTF-16 and rule-index contract, and pin the null-text argument check.
Program.Clone deep-copied the SubPrograms dictionary but left every
SubProgramCall pointing at the source's sub-program, and
SubProgramCall.Clone went through the Rotation setter, which re-rotated
that shared program to the call's stale angle. Copying a program with
hole lead-ins therefore rotated the source's holes, and rotating the
copy rotated the source again.
Program.Rotate also rotated a shared sub-program once per call, so two
identical holes (one deduplicated sub-program) turned twice.
Clone now binds calls to one private copy per shared sub-program
without re-aligning it, and Rotate turns each distinct sub-program once.
RapidEnumerator primed the walk position at the first pierce point, then
the skipped first rapid advanced it again. Raw programs start with a zero
rapid so this was invisible, but lead-in programs start with a real
incremental offset to the pierce, which shifted every later rapid by that
delta and drew rapids off the sheet. Start the walk at the program origin.

Min/max were seeded at 0, so any geometry not touching the origin got an
inflated box, and the first move only updated max (else-if). Rotated
canonical drawings are the common trigger: their origin ends up outside
the shape, which skewed Part bounds and bbox-based alignment.
Track the real extents and keep returning a zero box for empty programs.

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.
Pulls the rapid-walk logic (sub-program unwrapping, first-pierce lookup,
incremental-vs-absolute handling, first-rapid skipping) out of
PlateRenderer.DrawRapids into a reusable RapidEnumerator in Core so it
can be unit-tested and reused outside the renderer.

Adds Dictionary<string,string> VariableRefs to Motion (cleared on Rotate/Offset) and string VariableRef to Feedrate, with deep-copy Clone() support, so post processors can emit variable references instead of literal coordinate values.

Adds immutable VariableDefinition record to OpenNest.CNC with name,
expression, resolved value, inline, and global flags. Fixes namespace
collision in PatternTilerTests and PolygonHelperTests caused by the new
OpenNest.Tests.CNC namespace.
