feat(assets): Implement basic asset packing system

Introduces a new asset management system to embed binary assets directly into the demo executable.

- Creates the  directory for asset definition and an  descriptor file.

- Implements  to generate  (with  enum and  declaration) and  (with placeholder data).

- Integrates  into CMake build, making  depend on the generated asset files.

- Adds minimal integration in  and documentation in .

This addresses Task 9 (compact in-line and off-line asset system).
