v3.6: Defense System Disabled + Per-Pokemon Tick Optimization

Part A — PokemonDefenseSystem Disabled

1. Removed PokemonDefenseSystem.register() from CRZbrainMod — no more tick handler (entity search every 1s for ALL Pokemon) and no damage listener
2. Removed all PDS calls from PokemonCommandSystem — executeProtect(), executeActiveDefense(), executeAggressiveMode(), executeGuardMode(), executeStandDown() no longer call PokemonDefenseSystem
3. Simplified updateDefendingState() — removed findHostilesNearPlayer() entity search, now just follows player (teleport if distance > 5.0)
4. Simplified updateProtectingState() — removed findHostilesNearPlayer() entity search, now just stays near player (teleport if distance > 3.0)
5. Disabled defense commands in Commands.kt — setDefenseMode(), showDefenseStatus(), showAllDefenseStatus(), activatePvPMode() all return "Sistema difesa disabilitato (v3.6)"
6. Removed PDS.resetPokemon() from PokemonLifecycleManager
7. Removed unused imports — PokemonDefenseSystem import removed from CRZbrainMod, Commands, PokemonCommandSystem, PokemonLifecycleManager

Part B — TickOptimizationSystem (New Unified Tick Dispatcher)

1. Created sensors/TickOptimizationSystem.kt — single ServerTickEvents.END_SERVER_TICK handler replaces 3 separate handlers
2. Strategy 1 — Temporal Staggering: Pokemon split into 2 groups via uuid.hashCode() % 2, updated on alternating ticks (halves peak load per tick)
3. Strategy 2 — Distance-Based LOD: Pokemon >16 blocks from trainer (squaredDistanceTo > 256) skip every other update cycle (recalculated every 20 ticks)
4. Strategy 3 — Frequency Reduction: Combat states stay at 10-tick interval, non-combat states (FOLLOWING, EXPLORING, DEFENDING, PROTECTING) doubled to 20 ticks; WorldEventSystem interval doubled from 600 to 1200 ticks (30s → 60s)
5. Strategy 4 — Intelligent Batching: getActivePokemon() cached per player with 10-tick TTL (was called ~28 times per cycle, now 1); single player iteration loop instead of 3 separate loops
6. Removed tick handler from PokemonCommandSystem — exposed updateSinglePokemon() public method, removed lastUpdateTick and UPDATE_INTERVAL
7. Removed tick handler from WorldEventSystem — renamed checkWorldEvents() to checkWorldEventsForPlayer() and made it public, removed lastCheckTick and CHECK_INTERVAL_TICKS
8. Removed tick handler from PokemonRelationshipSystem — added tickForPlayer() public method, removed lastInteractionTick and INTERACTION_COOLDOWN_TICKS
9. Cache invalidation hooks — TickOptimizationSystem.invalidateCache() called on POKEMON_SENT_POST and DISCONNECT events; cleanup() called on SERVER_STOPPING
10. handleSpontaneousDialogue() uses cached Pokemon list instead of calling PokemonUtils.hasActivePokemon() directly
11. Removed unused imports — ServerTickEvents removed from WorldEventSystem, PokemonRelationshipSystem; HostileEntity/AnimalEntity/PlayerEntity removed from PokemonCommandSystem
