v1.0.0

First stable release. The public API is now committed to semantic versioning. Headline items: stabilized core (reprs, view returns, exceptions, copy / deepcopy / pickle, equality), new I/O (compressed HIF, AHORN, Hypergraphx-Data), nested generators, consistent generator naming, embedded nodes in multilayer plots, local RNG state, discoverable stats, and a shipped xgi.skill package for AI pair programming.
