This PR introduces the ability to exclude certain paths from the file watcher in Deno. This is particularly useful when running scripts in watch mode, as it allows developers to prevent unnecessary restarts when changes are made to files that do not affect the running script, or when executing scripts that generate new files which results in an infinite restart loop. --------- Co-authored-by: David Sherret <dsherret@gmail.com>
