feat(pkg): opencv module 0.0.6 → macOS (import opencv.cv via clang forwarding layer)

opencv-m v0.0.6 added the clang static-inline export forwarding layer (26 core
names), so clang (macOS) can now compile+link `import opencv.cv;`. Re-point:
- pkgs/o/opencv.lua: 0.0.4→0.0.6, +xpm.macosx (OS-neutral module tarball, sha adebd6b1…).
- opencv-module + opencv-module-unifont → +cfg(macos); guards __linux__→__linux__||__APPLE__.
- opencv-module-dnn stays linux (dnn x86; blocked on mcpp#253 per-OS features).
The macOS workspace leg is the definitive clang link+run validation of v0.0.6.
