### Fixed

- Raised the AbstractVision floor to `abstractvision>=0.3.4` across Gateway
  install profiles so `abstractgateway[gpu]` and the NVIDIA image inherit the
  stable-diffusion.cpp binding constraint that avoids the broken
  `stable-diffusion-cpp-python==0.4.6` Linux sdist.
- Updated release-facing Docker examples and package metadata from `0.2.5` to
  `0.2.6`.
- Release/CI installs now bypass the restored pip dependency cache for editable
  dependency resolution, avoiding stale package indexes immediately after
  lower-package releases.
