The distro OCIO is too old for the bridge's API floor where it matters
(Ubuntu 24.04 ships 2.1; the bridge uses 2.4+ APIs), and version drift
across platforms is a support hazard — enable ocio-rs' bundled feature
and drop the OCIO_INSTALL_DIR/system-package wiring from CI and CD so
Linux, macOS and Windows all build the same vendored OCIO. cmake/make/
diffutils added where the runners lack them (Windows FFmpeg build needs
make + cmp).
- save() writes <config>/config.toml (atomic temp+rename), flat keys
at the top level and group/sub keys as [group] tables, values as
native TOML int/float/bool/string (non-finite doubles degrade to
strings and restore via the declared type)
- load() prefers config.toml; a legacy config.ini (C++ or pre-TOML
Rust builds) is read once and immediately re-persisted as TOML; the
INI file is left in place; a corrupt TOML is reported, never
silently discarded
- cd.yml: drop a stale oakengine comment (the crate is retired)
