fix(engine): enforce whole-job safety invariants

Task 5 of the whole-job engine API: add a geometry safety gate that validates every candidate trial before the runner commits accounting. - NestJobPlacementValidator: closed-contour validity, rotation-policy compliance, work-area containment per quadrant, hole-aware material overlap, and required part spacing. Overlap is interior-only, so zero-clearance edge/corner contact remains a valid placement. - NestJobValidator: route candidate validation through the geometry gate; reject unusable/unclosed/degenerate contours up front. - NestJobRunner: wrap candidate evaluation in a progress bridge that tags legacy engine detail with the current candidate context. - LegacyPlateNesterAdapter: forward IProgress to the legacy engine so its progress surfaces under the active candidate. - Tests: geometry (quadrants, rotations, touching, containment, holes, empty stock, real Default/Strip smoke), validation, and cancellation suites; repaired test fakes that emitted out-of-bounds or overlapping placements the gate now correctly rejects. Engine.Tests: 70 passed, 0 failed, 0 skipped in Debug and Release. Windows-only OpenNest.Tests not run on Linux.
