Added

• The player's manual ships with the game. Releases now carry
  docs/Manual.html next to the executable — the loop, every key, all six
  contests, and the tips worth knowing — so game managers that offer a
  game's documentation, like AGNow, find something a player would actually
  read.

Changed

• The manual is the only document a release offers a player. A game
  manager scanning the install folder used to list numpy's
  entry_points.txt, setuptools' vendored lorem ipsum and thirty-odd
  dependency licenses buried in _internal alongside the manual. The
  packaging bookkeeping is gone. The licenses still ship — they have to —
  merged into a single extensionless Third-Party-Licenses file at the
  bundle root, where the MIT license now also sits as LICENSE: present
  for anyone who looks, never offered as something to read.
• Design notes moved from docs/DESIGN.md to DESIGN.md at the
  repository root, leaving docs/ player-facing by contract. The README's
  How to play section now points at the manual instead of duplicating it.
