Register component clone and copy into type registry

[waynemwashuma]

Objective

Integrate copy / clone semantics into the type registry system.

• Registers duplication methods for all ECS components in their respective modules
• Enables reflection-based systems to invoke component-specific duplication logic
• This is building upon Add Typeinfo method registration #307

Solution

Although copy / clone methods were introduced on components, they were not discoverable through the type registry. This adds a way to use the type registry to clone/copy components in reflection based systems without needing to know the underlying type.

Changes made

Added method registrations for  ``copy and clone across all registered component types.

Why this approach

• Enables generic systems to invoke copy/clone without hardcoding types
• Aligns duplication with existing metadata-driven workflows

Showcase

Before

// Registry cannot perform cloning generically

const info = registry.get(Position2D)

// No way to invoke type-specific copy logic
// Requires manual handling per type

After

const info = registry.get(Position2D)

// Invoke registered method (pseudo-API)
const copy = info.call('copy', source)
