### Changed
- Moved AbstractCore remote/tool/media capability integration and the MCP worker dependency set into the base `pip install abstractruntime` profile. Runtime now exposes only the base, `abstractruntime[apple]`, and `abstractruntime[gpu]` user install profiles for functionality vs. local-inferencer selection; the `abstractcore`, `multimodal`, `mcp-worker`, `all-apple`, and `all-gpu` extras are no longer part of the supported install surface.
- Raised the AbstractCore dependency floor to `abstractcore>=2.13.31` so Runtime installs inherit the latest remote-light media and Wan A14B vision contracts.

### Fixed
- Local text-to-video and image-to-video media-only calls now run in an isolated subprocess, preserving progress callbacks while preventing native MLX/Metal video failures from killing the Gateway/Runtime parent process.
