DValue dir_list(String path)

:params
path : directory to list
return value : a list of entry maps, each with name, type, size, mtime

:content
Lists a directory's entries as a `DValue` list. Each entry is a map with `name`, `type` ("file", "dir", "symlink", or "other"), `size`, and `mtime`. Iterate with `.each()` and read fields with `item.key("name")->to_string()`.

:example
mkdir("/tmp/doc-dirlist");
file_put_contents("/tmp/doc-dirlist/note.txt", "hi");
DValue entries = dir_list("/tmp/doc-dirlist");
String found = "no";
entries.each([&](const DValue& item, String key) {
    if(item.key("name") && item.key("name")->to_string() == "note.txt")
        found = "yes";
});
print("note.txt listed: ", found, "\n");
