- the oak-editor release build lacked the
`windows_subsystem = "windows"` crate attribute, so launching the
installed app opened a console window next to the editor (debug builds
keep the console so `cargo run` shows logs);
- oak-worker, the OFX host and the ffmpeg/ffprobe helpers are
console-subsystem binaries spawned by the GUI app, so each spawn now
carries CREATE_NO_WINDOW through the shared
oak_core::miscutils::hide_console_window helper (a no-op off Windows).
