Adds a Coordinate conventions section to packages/mcp/README.md and a 71-node MCP demo scene that exercises every claim it makes. Closes#337.
Covers: right-handed scene with X/Z ground plane and Y up; metres for lengths and radians for rotations as Euler [x, y, z]; the [x, z] → (x, y, z) plan-to-world mapping with no sign flip in the stored contract; level/building-local framing (world only under identity transform); rotation-not-reflection caveat for the 2-D plan panel and the iso-default top-down azimuth offset; a worked 30° rotated slab example; and the wall-local-metres trap for door/window/place_item coordinates.
Companion: examples/coordinate-conventions-demo.{json,md} with a reference compass at the origin and Demos A/B/C/D illustrating axis-aligned baseline, the rotated example, and the page-intent vs world-result L pair.
