nightshade-editor-0.36.1 is not a library.
Standalone editor: hosts the same web bundle the browser runs, served from
a local port into a native webview window. The build script stages the
bundle: a local trunk build when one exists, otherwise the published
bundle downloaded from the matching GitHub release. Debug builds read the
staged copy from disk so a fresh trunk build shows up on the next run;
release builds embed it into the executable.
