Description

Interface for handlers that process spawn and despawn commands.

SpawnCommandHandler defines the contract for managers that handle entity lifecycle operations for GameObjectPools. Each handler is registered with a SpawnProfileId via `GameWorld::registerSpawnCommandHandler()`.

When a pooled entity needs to spawn or despawn, the appropriate handler is looked up by profile ID and receives the command for deferred processing.

## Command Types

**SpawnCommand:** Commands acquisition of an entity from the pool
**DespawnCommand:** Commands return of an entity to the pool
**ScheduledSpawnPlanCommand:** Commands batch spawning from scheduler

## Implementation Notes

Handlers typically also implement the Manager interface to receive flush() calls for deferred command processing during the manager flush phase.

Example: ```cpp class MyPoolManager : public Manager, public SpawnCommandHandler { bool submit(const SpawnCommand& cmd) noexcept override { spawnQueue_.push(cmd); return true; } bool submit(const DespawnCommand& cmd) noexcept override { despawnQueue_.push(cmd); return true; } bool submit(const ScheduledSpawnPlanCommand& cmd) noexcept override { planQueue_.push(cmd); return true; } void flush(GameWorld& world, UpdateContext& ctx) noexcept override { // Process queued commands } }; ```
