bump version a 0.8.1

- Nou enemic STAR amb shape star_5.shp, escala 0.7 i color groc pur.
  Reusa el comportament zigzag del Pentagon i carrega via EnemyRegistry.
- DistribucioEnemics estesa amb camp 'star' opcional (default 0) per
  mantenir compat amb stages antics.
- Stage 1 reconfigurat a 25/25/25/25 per mostrar els 4 tipus.
- Afegits també shapes bullet_long.shp i bullet_double.shp (encara no
  utilitzats; preparats per futures variants de bala).

+// define_inputs.hpp - Overlay modal de redefinici de controls (singleton)
+// © 2026 JailDesigner
+//
+// Sub-mòdul inspirat en aee_arcade/source/core/input/define_buttons. Quan el
+// menú de servei dispara una acció "Redefinir tecles/botons P1/P2", aquest
+// singleton pren el control: pinta una caixa central, captura events SDL i
+// avança per una seqüència fixa d'accions, persistint les noves assignacions
+// a config.yaml en acabar.
+//
+// Cicle de vida:
+//   1. begin(mode, player) → construeix la seqüència (4 passos) i activa
+//      l'overlay. Per a GAMEPAD, retorna false si el jugador no té pad.
+//   2. handleEvent() captura el següent event vàlid; ESC cancel·la sense
+//      desar; duplicats dins de la sessió es rebutgen silenciosament.
+//   3. Quan la seqüència es completa, persistim a engine_config + saveToFile,
+//      reapliquem els bindings i mostrem un missatge "OK" durant 1.5 s
+//      abans d'auto-tancar-se.
+//
+// El routing d'events es fa des de GlobalEvents::handle: mentre isActive()
+// retorna true, tots els events SDL es desvien aquí i no arriben al joc ni
+// al menú de servei.
