### Fixed
- Gateway's base install now avoids mixing Core's narrow base media/embeddings extras with Core `[all-apple]` and `[all-gpu]` profile dependencies, while still installing the media, compression, and embeddings dependency set needed by the remote-capable base package.
- Gateway's base media dependency set now uses a Python-3.10-compatible `unstructured` line and bounds `python-pptx` to supported modern releases so document-capable installs do not backtrack into broken legacy setup packages.
- Gateway's base web dependency set now prefers current compatible FastAPI/Uvicorn/Requests/urllib3 releases to keep CI and user installs out of unnecessary resolver backtracking.
- Gateway now applies a compatible setuptools lower bound so Apple/GPU installs satisfy Torch's `<82` constraint without resolving into ancient broken setuptools releases.

### Changed
- Raised the Runtime floor to `AbstractRuntime>=0.4.13` so Gateway profiles consume Runtime's updated multimodal dependency metadata, and raised the Music floor to `abstractmusic>=0.1.2`.
