CI / Build & test (Windows) (push) Failing after 7s
All crates take the oak-* kebab-case naming (oak-audio, oak-codec, oak-common, oak-core, oak-ffmpeg-link, oak-node, oak-otio, oak-plugin, oak-render, oak-storage, oak-task, oak-timeline, oak-undo), with the lib identifiers rewritten (oakrender:: -> oak_render::, oakcore_rs:: -> oak_core::, ...) across all 226 referencing files. The GUI application moves from the workspace root into crates/oak-app/: src/, build.rs (paths fixed for the new location) and tests/ travel with it, the root Cargo.toml becomes workspace-only ([workspace] + workspace.package + profiles), and the app package inherits the workspace version. The screenshots example becomes a standalone crate examples/simple_player/ with its own Cargo.toml. Every crate now inherits the single workspace version (version.workspace = true), and the workflows' crate paths and the build docs follow the renames. Validated with a clean cargo check --workspace.
