Roof Takeoff API and MCP

Calculates a complete roof takeoff from actual final measurements or plan-view measurements adjusted for roof pitch. Accessible to humans via the builder UI, to AI agents via GET calculation URL, REST API, and MCP tools - all using the same shared calculation engine. The human builder, REST API, result page, and MCP tools all use the same calculation engine.
