feat(03-05): ajoute RegionVisualizer (parsing hex/mode, throttling, low-level DebugUtils.add) (Task 2)

- RegionVisualizer emet DisplayDebug cube par region via
  DebugUtils.add(World, DebugShape.Cube, Matrix4d, color, opacity, time, flags)
  (low-level => opacity custom respectee, vs addCube qui hardcode 0.8).
- Mapping modes: Outline=FLAG_NO_SOLID, Faces=FLAG_NO_WIREFRAME, Both=FLAG_NONE,
  None=skip, unknown=fallback Outline.
- parseColor(#RRGGBB) avec fallback COLOR_CYAN sur input invalide.
- Throttling par region via ConcurrentHashMap<name, lastEmitMs> + clock injecte.
- Clamp defensive: VisualRefreshMs plancher 100ms (anti-DoS T-03-05-03),
  VisualOpacity clamp [0,1] (T-03-05-04).
- TTL = refreshMs * 1.2 / 1000 (overlap 20% anti-flicker).
- Toute emission wrappee dans world.execute(...) via WorldExecutor injectable.
- Tests: parseColor valid/invalid, normalizeMode, flagsForMode, matrixFromBox
  non-cubique, throttling deterministe, skip None/disabled, clamp opacity/refresh.

/**
* Plan 03-05 : service qui émet des cubes debug (DisplayDebug / ClearDebugShapes) pour
* matérialiser chaque région de gravity-flip côté clients. Ne crée aucun scheduler ;
* {@link #visualize(World, RegionSnapshot)} est appelé à chaque tick par
* {@code RegionTickLoop}, avec throttling par région via {@code VisualRefreshMs}.
*
* <p><b>Mapping VisualMode → flags</b> (cf. {@link DebugUtils}) :
* <ul>
* <li>{@code "Outline"} → {@link DebugUtils#FLAG_NO_SOLID} (wireframe uniquement).</li>
* <li>{@code "Faces"} → {@link DebugUtils#FLAG_NO_WIREFRAME} (faces uniquement).</li>
* <li>{@code "Both"} → {@link DebugUtils#FLAG_NONE} (wire + solide).</li>
* <li>{@code "None"} → skip (aucune émission).</li>
* <li>autre / null → fallback {@code "Outline"}.</li>
* </ul>
*
* <p><b>Opacity caveat</b> : {@link DebugUtils#addCube} hardcode {@code opacity=0.8} ;
* on passe donc par le low-level {@link DebugUtils#add(World, DebugShape, Matrix4d, Vector3f, float, float, int)}
* qui accepte l'opacity custom. TTL = {@code refreshMs * 1.2 / 1000} (overlap 20 %
* pour éviter le flicker entre deux émissions).
*
* <p><b>Threading</b> : {@code lastEmitMs} est un {@link ConcurrentHashMap} car
* {@code RegionTickLoop} tourne sur un thread daemon séparé. Chaque appel
* {@link DebugUtils} est wrappé dans {@code world.execute(...)} pour satisfaire
* l'assert WorldThread (pattern identique à {@code RegionRegistry.refreshFor}).
*
* <p><b>Anti-DoS</b> : {@code VisualRefreshMs} est clampé à un plancher pour
* empêcher une valeur pathologique (0 ou très petite) de saturer les clients
* avec des paquets {@code DisplayDebug}.
