ajandClaude Opus 4.6 3dca25c601 fix: improve circle nesting with curve-to-curve distance and min copy spacing
Add Phase 3 curve-to-curve direct distance in CpuDistanceComputer to
catch contacts that vertex sampling misses between curved entities.
Enforce minimum copy distance in FillLinear to prevent bounding box
overlap when circumscribed polygon boundaries overshoot true arcs.

ajandClaude Opus 4.6 ebc1a5f980 refactor: extract shared helpers in SpatialQuery
Pull duplicated vertex collection, edge conversion, sorting, and

ajandClaude Opus 4.6 b729f92cd6 fix: correct compactor circle-to-circle directional distance
The vertex-to-entity approach in DirectionalDistance only sampled 4
cardinal points per circle, missing the true closest contact when
circles are offset diagonally from the push direction. This caused
the distance to be overestimated, pushing circles too far and
creating overlap that worsened with distance from center.

Add a curve-to-curve pass that computes exact contact distance by
treating the problem as a ray from one center to an expanded circle
(radius = r1 + r2) at the other center. Includes arc angular range
validation for arc-to-arc and arc-to-circle cases.

ajandClaude Opus 4.6 5d6e018b81 fix: preserve circle rotation direction through geometry round-trip
Circle.Rotation was lost in three places, causing reversed circles to
still offset inward instead of outward:
- ConvertGeometry.AddCircle hardcoded CCW instead of using circle.Rotation
- ConvertProgram.AddArcMove created Circle without setting Rotation from arc
- Shape.OffsetOutward/OffsetInward copied Circle without setting Rotation

ajandClaude Opus 4.6 cca70db547 fix: consolidate tail plates by upgrading instead of creating new plates
Three fixes to TryUpgradeOrNewPlate and a new post-pass:

1. Change ShouldUpgrade from < to <= so upgrade wins when costs are
   tied (e.g., all zero) — previously 0 < 0 was always false

2. Guard against "upgrades" that shrink a dimension — when options are
   sorted by cost and costs are equal, the next option may have a
   smaller length despite higher width (e.g., 72x96 after 60x144)

3. Revert plate size when upgrade fill fails — the plate was being
   resized before confirming parts fit, leaving it at the wrong size

4. Add TryConsolidateTailPlates post-pass: after all nesting, find the
   lowest-utilization new plate and try to absorb its parts into
   another plate via upgrade. Eliminates wasteful tail plates (e.g.,
   a 48x96 plate at 21% util for 2 parts that fit in upgraded space).

Real nest file: 6 plates → 5 plates, all 43 parts placed.

LoadLastPlate, LoadNextPlate, LoadPreviousPlate, IsFirstPlate, IsLastPlate,
EnsureSentinelPlate, CurrentPlateIndex, PlateCount) with direct access to

- Reactive tail subscriptions (PartAdded/PartRemoved on last two plates) call EnsureSentinel automatically; re-subscribed after each plate list change
- BeginBatch()/EndBatch() defers sentinel enforcement during bulk operations
- GetOrCreateEmpty() returns or creates an empty plate; RemoveCurrent() removes the current plate with index clamping; CanRemoveCurrent guards deletion

- Strategies now promote results to IsOverallBest when they beat the

  than waiting for each phase to complete
- PlateView only updates the main view on overall-best results, fixing
  intermediate angle-sweep layouts leaking to the plate display
- Skip Row/Column strategies for rectangle parts (redundant with Linear)
- Intercept Escape key at MainForm level via ProcessCmdKey so it always
  reaches the active PlateView regardless of focus state
- Restore keyboard focus to PlateView after fill progress form closes
- Remnant engines use SelectBestFitPair for orientation-aware pair
  selection; DefaultNestEngine tries both landscape and portrait pairs
- RemnantFiller preserves more parts during topmost-part removal

Always keep a trailing empty plate so users can immediately place parts
without manually adding a plate. Auto-appends a new sentinel when parts
land on the last plate; trims excess trailing empties on removal.

Plate list now shows Parts count and Utilization % columns. Empty plates
are filtered from save and export. Sentinel updates are deferred via
BeginInvoke to avoid collection-modified exceptions and debounced to
prevent per-part overhead on bulk operations.

ajandClaude Opus 4.6 ef15421915 refactor: standardize fill strategy progress reporting via FillContext
Strategies and fillers previously called NestEngineBase.ReportProgress
directly, each constructing ProgressReport structs with phase, plate
number, and work area manually. Some strategies (RectBestFit) reported
nothing at all. This made progress updates inconsistent and flakey.

Add FillContext.ReportProgress(parts, description) as the single
standard method for intermediate progress. RunPipeline sets ActivePhase
before each strategy, and the context handles common fields. Lower-level
fillers (PairFiller, FillExtents, StripeFiller) now accept an
Action<List<Part>, string> callback instead of raw IProgress, removing
their coupling to NestEngineBase and ProgressReport.

BuildOffsets had Width and Length swapped after the Box axis correction

spiral+center vs full best-fit fairly. BestCombination returns a
