Layout caching moved onto the nodes themselves

Layout data moved onto each node, and mixing layout configurations now raises an error.

What

Cached layout rectangles and pending-clear tracking now live on each layout node rather than in a side lookup table, and the counters for nodes visited, measure calls and cache hits moved onto the layout configuration object. Adding a child created under a different configuration now raises an error instead of producing inconsistent layout.

Evidence

insertChild: child was created with a different Config

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
