Single mechanical restructure commit: - root Cargo.toml = oakapp bin + workspace; one cargo build produces oakapp, oak-cli, oak-worker, liboakengine.dylib - app/rust/src -> src/ (app at repo root, no rust/ nesting) - src/<mod>/rust -> crates/oak<mod>; src/oakcore-rs -> crates/oakcore; src/bindings/oakotio -> crates/oakotio; src/engine/rust -> crates/oakengine (keeps cdylib+staticlib+rlib) - public C headers include/<mod>/ -> crates/oakengine/include/<mod>/ - OFX SDK headers vendored into crates/oakplugin/ofx/ (HostSupport gone) - legacy deleted: old src/ C++ modules, engine/, core/, ffmpeg_bridge/, app/ (Qt), cli/worker C++, root CMakeLists, third_party/KDDockWidgets submodule, otio-install, all build-* output (~40GB) - oakstorage kept but excluded from the workspace (skeleton w/ todos); gpui excluded (own workspace) - verified: cargo build green, cargo test --workspace 1845/0 (with the documented OCIO_RS_* env override for the homebrew OCIO)
