Hnefatafl: Copenhagen and Tablut, a board that ages with the older game, and a bot that looks three moves ahead

The rules are data in rules.ts; the engine plays custodial capture, the
king's own capture rule on and beside the throne, corner and edge
escape, shieldwalls, edge forts, encirclement, repetition and stalemate;
twenty tests pin them and play a bot game to a verdict on both boards.

+# Hnefatafl
+
+The Viking board game, in the browser: the attackers must take the king, the
+king must reach a corner. Copenhagen rules on the eleven-by-eleven board by
+default; Tablut, the nine-by-nine game Linnaeus wrote down in 1732, as an
+option, on a board that shows its age.
+
+Built on the game kit: `src/lib/game/` is the game (rules as data in
+`rules.ts`, the engine in `index.ts`, a short alpha-beta bot in `bot.ts`),
+`src/lib/components/Board.svelte` is the board, and everything else is the
+kit's hall, tables, gallery, ledgers, reports desk and ops tools.
+`docs/conventions.md` is the house style.
