Remove reaction boss bar; fix death coords; F-tribute head

- Reactions: drop the purple boss bar that sat on screen for the whole
  reaction window (curiosidades, adivinha, luto [F], /ia answers). Live
  counts still ride on the reactor's action bar and the closing tally line.
- mortes: death coordinates were sent during PlayerDeathEvent and the Java
  death screen swallowed them. Capture at death, deliver on PlayerRespawnEvent
  (1 tick later) so the player actually receives them. Respects keepInventory.
- luto: pressing F to pay respects now drops the dead player's head into the
  mourner's inventory — once per mourner per death, never to the dead player.
  First gameplay-touching feature; toggle with luto.cabeca (default on).
- Fix the /f typed twin: it fell through to help because "f" is not a
  configured reaction (the mourning set is hardcoded). Route it to reactLatest
  so Bedrock players can pay respects too.
- README + config updated. 117 tests green.
