ResourceLayers.lean — Combined Base + Topological Resource Layers

Replaces scripts/combined_resource_layers.py with a formal Lean module
that defines physical and topological resource layer structures and calculations.

Per AGENTS.md:
  - Q16_16 for scoring (§1.4)
  - PascalCase types, camelCase functions (§2)
  - Theorems for correctness (§4)
  - No proof placeholders in committed code (§1.6)
