v6.3.0

Added

• The server now introduces itself. initialize returns a titled, described
  serverInfo (name, title, description, websiteUrl) plus instructions that
  tell the client's model the server is exclusively about Pokémon Champions —
  doubles, level 50, Mega Evolution, 66 stat points, Regulation Sets M-A–M-C —
  and how the eight mode-dispatching tools and six prompts hang together.
  Every tool description now names the game too, so a client that only
  surfaces the tool list still knows what it is connected to, and the npm
  description says so for directory listings.
