UniversalAdmin 1.7.0

Staff can play incognito now.

Added

• Nick system, a new built-in module: /nick Notch shows you as Notch,
  with Notch's skin, in the chat, the tab list, above your head, in join,
  quit and death messages and to other plugins. Name and skin can be chosen
  separately (/nick Bob Notch), or both at random (/nick random);
  /unnick ends it, also from the new Nick menu. Names of players who
  have played here, of online players and of other nicks are refused. Staff
  with universaladmin.nick.see see the real name in the player list, on
  the profile and in /nick list; punishments, notes, reports and the
  audit log keep the real identity, and actions a nicked staff member takes
  run under their real name. A nick survives rejoining
  (nick.restore-on-rejoin) and follows its player through a network. See
  docs/user/modules/nick.md and
  ADR 0025.
• UniversalAdmin TAB, an official extension for TAB: nicked players are
  shown in an ordinary TAB group, vanished staff and players in staff mode
  get a marker. Its own repository:
  universaladmin-mc/universaladmin-tab.
• Extension API 1.6: the Nicks service (dev.universaladmin.status),
  PlayerNames.real(...) and PlayerNames.revealedTo(...).
• Vanish sets the vanished player metadata vanish plugins share, so TAB,
  map plugins and others recognise UniversalAdmin's vanish.

Fixed

• On Java 21 the update check and the anonymous statistics did not start
  ("No implementation of the random number generator algorithm").
• A player who left while vanished came back invisible when
  moderation.vanish.restore-on-reconnect was off.
