Add deferred resource commands

[waynemwashuma]

Objective

Introduces a command-based API for deferred resource operations for adding, removing, and aliasing resources.

Solution

Resource changes are now represented as commands and queued through the world's existing CommandQueue. The operations are applied when the command execution system processes the queue.

Changes Made

The following changes were introduced:

• Added AddResourceCommand to add a resource.
• Added RemoveResourceCommand to remove a resource.
• Added SetResourceAliasCommand to assign a resource alias.
• Added ResourceCommands as a higher-level API for queuing the three operations.

Why This Approach

This solution was chosen because:

• Resource mutations can be deferred and executed through the existing command queue.
• Resource operations follow the same command-based workflow used elsewhere in the core.
• The implementation avoids directly mutating the world when the resource operation is requested.

Showcase

Before

Resource mutations had no dedicated command API for queuing resource additions, removals, or aliases.

After

Resource operations can be queued through ResourceCommands:

const commands = new ResourceCommands(world)

commands
  .add(resource)
  .remove(ResourceType)
  .setAlias(typeid(ResourceType), ResourceAlias)

The corresponding operations are then applied when the command queue is executed.
