Add Vector-based overloads to SpatialQuery (ray casting, edge distance,
directional gap, perpendicular overlap) and PartGeometry (directional
line filtering) to support pushing parts along any angle, not just
cardinal directions.
Add Compactor.PushBoundingBox for fast coarse positioning using only
bounding box gaps. ActionClone shift+click now uses a two-phase strategy:
BB push first to skip past irregular geometry snags, then geometry push
to settle against actual contours.

- FillExtents.Fill reported progress internally which overwrote the UI's
temporary parts even when a better result (e.g. Pairs with 70 parts)
won the competition. Added final ReportProgress call in FindBestFill
and Fill(groupParts) to ensure the UI always shows the actual winner.
- FillExtents vertical copy distance clamp (Math.Max with pairHeight +
spacing) prevented geometry-aware compaction from ever occurring,
causing visible gaps between rows. Boundaries are already inflated by
halfSpacing so the calculated distance is correct; only fall back to
bounding-box distance on non-positive results.
- PairFiller now sets RemainderPatterns on FillLinear so remainder strips
get pair-based filling instead of only individual parts (+1 part in
tight layouts).

Adds FillExtents as a fourth nesting phase in both FindBestFill and
Fill(groupParts, Box), running at bestRotation and bestRotation+90°.
Updates Description to reflect the new phase.

Replace RepeatColumns stub with real implementation: compacts a test column
left against column 1 to derive the copy distance, tiles further columns at
that interval, and clips partial columns to the work area bounds. Adds 4 new
FillExtentsTests covering multi-column fill, rect shapes, non-zero-origin
work areas, and cancellation.

Replace AdjustColumn stub with a convergence loop that distributes the
remaining gap between the topmost part and the work area top edge across
all pairs. TryAdjustPair/TryShiftDirection try shifting part2 up (or down
as fallback) and compact left, rejecting moves that widen the pair.

The Size fix (d4222db) changed Size.Width to Y axis and Size.Length to
X axis but only updated DrawPlate/LayoutViewGL. BoundingBox, WorkArea,
rotations, DXF export, and engine code still used the old Width=X
convention, causing the fill engine to get a swapped work area (60x120
instead of 120x60) and parts to fill in the wrong direction.

Longest edges produce the flattest tiling rows and should be tried
first. Also deduplicates angles before sorting.

FillLinear now accepts optional RemainderPatterns that are tried in
leftover strips after the main grid fill, improving packing density
when pair patterns fit the narrow residual space.

Two bugs caused the remnant finder to miss valid empty regions:
1. RemoveDominated used an 80% overlap-area threshold that incorrectly
removed L-shaped remnants. A tall strip to one side would "dominate"
wide strips above/below it even though they represent different usable
space. Replaced with geometric containment check — only remove a box
if it's fully inside a larger one.
2. FindTieredRemnants split remnants at the obstacle envelope boundary,
and both pieces could fall below minDimension even though the original
remnant passed the filter (e.g., 6.6" remnant split into 5.35" + 1.25"
with minDim=5.38"). Added fallback to keep the original unsplit.

Add plate-free Push overload and CompactIndividual method that pushes
each part individually against all others as obstacles. Disabled in
StripNestEngine pending investigation — compaction opens irregular gaps
that the remnant finder scatters parts into.

Skip remnants that are too small to fit any remaining part, avoiding
wasted fill attempts. Recalculated each iteration as quantities deplete.

Remainder items were being filled into the full remnant box without
compaction. Added ShrinkFill helper that fills then shrinks the box
horizontally and vertically while maintaining the same part count.
This matches the strip item's shrink behavior and produces tighter
layouts that leave more usable space for subsequent items.

The iterative remnant fill was mutating shared NestItem.Quantity objects,
causing the second TryOrientation call (left) to see depleted quantities
from the first call (bottom). Use a local dictionary instead so both
orientations start with the full quantities.

Replace the single-pass guillotine split approach with RemnantFinder-based
iteration. After each fill, re-discover all free rectangles and try all
remaining items again until no more progress is made. This fills gaps that
were previously left empty after the initial strip + remainder layout.
Also change ActiveWorkArea border color from orange to red.

ComputeRemainderWithin only returned the larger of two possible free
rectangles, permanently losing usable area on the other axis after each
remainder item was placed. Replace the single shrinking box with a list
of free rectangles using guillotine cuts so both sub-areas remain
available for subsequent items.
