Await preprocessor worker disposal during teardown (
b7edcb7)
Vite now waits for CSS preprocessor workers to fully stop when the server/build tears down, instead of firing-and-forgetting the close calls. This fixes lingering Sass/Less/Stylus child processes and the related teardown bug reported in #22274.
Other misc changes
- Added a regression test covering Sass worker cleanup on
server.close().
