im not sure if this is easily done without cluttering general completions but it would be great if for example this

const std = @import("std");

pub const std_options = struct {
    pub const enable_se<cursor>
};

pub fn main() !void {}

gave a completion for enable_segfault_handler (maybe a type hint in the completion too? not sure how thatd work)
can zls detect if its in the root file? thats the only time std_options are valid
