✨ chore(scripts/utils, scripts/style-handler): add filter() method, change stylesheet target directory

the `filter()` function can both filter a common array and at the same time, it can also filter an Accessor Array(Accessor<Array<T>> and return an Accessor when provided Array is an Accessor Array. Stylesheet directory changed to colorshell's cache dir, making sense, since it's a temporary file generated by the shell
