FindCopyDistance and FindPatternCopyDistance were cloning entire Parts
(including deep Program copies) just to get offset locations for
GetLines. Compute offset locations directly instead. Also skip the
Pattern wrapper in TilePattern — clone parts directly.

Part.Clone() re-clones from the drawing's unrotated program, re-rotates,
and walks all CNC codes twice for bounding box — 4 O(c) passes per clone.
CloneAtOffset clones from the already-rotated program and computes the
bounding box arithmetically, reducing to 1 O(c) pass per clone.

Narrow remnant strips now get more parts by:
- Sweeping rotations every 5° when the strip is narrower than the part
- Including all pairs that fit the strip width (not just top 50 by area)
- Placing individual parts from incomplete pattern copies that still fit
- Using finer polygon tolerance (0.01) for hull edge angle detection

Extract MakeSeedPattern for shared part creation, and replace the
two-step primary/perpendicular tiling with a single FillRecursive
method that tiles along one axis then recurses perpendicular.

Extract offset polygon computation into PartBoundary, which builds
and caches inflated boundary polygons per unique part geometry.
FillLinear now uses symmetric half-spacing and reuses boundaries
across tiling passes, avoiding redundant offset calculations.

FindPatternCopyDistance now checks every pair of parts across adjacent
patterns so that multi-part patterns (e.g. interlocking pairs) maintain
correct spacing between ALL parts, not just the bounding boxes. The
original single-part logic is preserved as a fast path.

Offset the moving shape's geometry by PartSpacing instead of adding
spacing linearly to the copy distance. This guarantees minimum clearance
in all directions for curved/complex shapes, not just along the slide axis.

Merge ActionAddPart into ActionClone by adding a Drawing constructor,
eliminating the redundant class. ActionClone now handles both adding
new parts from a drawing and cloning selected part groups. Added
Ctrl+F fill support for groups using FillLinear pattern tiling, and
adopted quadrant-aware push directions from ActionAddPart. Refactored
FillLinear to extract shared helpers and add a Fill(Pattern) overload
for tiling arbitrary part groups across the work area.
