Detailed Description

Core container and data structures for EasyNav navigable meshes.

This header defines the fundamental types for NavMap:

• Vertex storage as a structure-of-arrays (SoA) via navmap::Positions.
• Triangle cells (navmap::NavCel) with cached geometry and adjacency.
• Surfaces (navmap::Surface) as partitions of triangles with their own BVH.
• A per-NavCel layer registry (navmap::LayerRegistry) to store arbitrary scalar attributes (occupancy, cost, elevation, etc.).
• The main navmap::NavMap container, including geometry queries such as raycast, closest-triangle and nav-cell localization.

The API exposes low-level containers while providing convenience utilities for common workflows without sacrificing control.
