Now we ensure that task output is fully drained and printed to Zed terminal pane on task completion. This change depends on a recent change to alacritty_terminal crate: https://github.com/alacritty/alacritty/commit/5e78d20c709cb1ab8d44ca7a8702cc26d779227c. Closes https://github.com/zed-industries/zed/issues/18342 Release Notes: - Fixed missing task terminal output on Linux for short-running commands
