Separate scene

[infirit89]

Closes: #52

[Copilot]

Pull request overview

This PR is part of the engine decoupling effort (#52 / #49) and moves the Scene system out of TerranEngine into a standalone LibScene, while also evolving the asset and logging infrastructure to support the new module layout.

Changes:

• Introduces Libraries/LibScene (Scene/Entity/Components/Serializer/Manager/Events) and wires it into premake + sandbox.
• Refactors LibAsset to use RefPtr-based assets and typed importer results (AssetLoadResult), adding handle/metadata changes.
• Adds/expands unit tests for LibScene, LibAsset, and LibCore plus updates CI coverage aggregation.

There are more changes/updates that need to be done to LibScene and LibAsset, however the foundational work is done here and in #55.

Thus I'm merging this and logging issues for further improvements.
