Subject: Refactor: Reorganize workspaces and remove assets/ directory
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Workspace structure now:
- workspaces/{main,test}/obj/      (3D models)
- workspaces/{main,test}/shaders/  (WGSL shaders)
- workspaces/{main,test}/music/    (audio samples)

Changes:
- Moved workspaces/*/assets/music/ → workspaces/*/music/
- Updated assets.txt paths (assets/music/ → music/)
- Moved test_demo.{seq,track} to tools/
- Moved assets/originals/ → tools/originals/
- Removed assets/common/ (legacy, duplicated in workspaces)
- Removed assets/final/ (legacy, superseded by workspaces)
- Updated hot-reload paths in main.cc
- Updated CMake references for test_demo and validation
- Updated gen_spectrograms.sh paths

handoff(Claude): Workspace reorganization complete
