Added

• Spectator Quick-Switch: Vanished players with vanishpp.spectator can double-tap Shift to toggle Spectator mode instantly. Double-tap again to return to the previous gamemode. Unvanishing while in Spectator forces the player back automatically (bypassed by vanishpp.spectator.bypass).
• spectator_gamemode VRule: New per-player rule to enable or disable the Spectator quick-switch. Default: true. Configurable globally under vanish-gamemodes.enabled.

Changed

• Spectator Mode Feedback: The action bar notification shown when entering or exiting Spectator mode is now displayed for 3 seconds and is no longer immediately overwritten by the vanish status indicator.
• Unknown Command on Permission Denied: Players without permission to use any Vanish++ command now receive a vanilla-style "Unknown command" response instead of a permission-denied message, preventing server staff plugin discovery.

Fixed

• Mob Despawning Near Vanished Players: Mobs no longer despawn when chunks are reloaded near a vanished player. The previous setAffectsSpawning(false) call incorrectly caused the server to ignore vanished players for mob lifecycle calculations. Pressure plate suppression is now handled exclusively by the CAN_TRIGGER_PHYSICAL rule, which was already in place.
• Mobs Not Attacking Non-Vanished Players: Removed MobAiManager, which replaced the vanilla LookAtPlayerGoal for all mobs globally. The Paper MobGoals API used to inject the custom goal was causing mob attack AI to break for all players. Attack prevention for vanished players is now handled entirely through EntityTargetEvent.
• can_throw Rule Had No Effect: Throwing projectiles (snowballs, eggs, ender pearls, potions, bows, crossbows) while can_throw was enabled was still blocked because PlayerInteractEvent cancelled the right-click before ProjectileLaunchEvent could fire. The interact handler now permits throwable items through when can_throw is enabled, even if can_interact is disabled.
• Spawn Eggs Always Blocked: Spawn eggs were blocked unconditionally regardless of the can_throw rule state. They now respect the rule correctly.
• Periodic Mob Pathfinding Interruption: The background sync task was calling stopPathfinding() on all nearby mobs every 0.5 seconds. This caused mobs to appear passive and disrupted vanilla mob behaviour for all players. Mob targeting is now handled reactively via EntityTargetEvent only.
