Pull Request Overview

This PR implements a multi-module system architecture for KernelSU by refactoring the existing codebase into a modular structure. It introduces a metamodule system that allows for pluggable module system implementations while maintaining backward compatibility.

• Creates a new ksu-core library containing shared utilities and constants
• Introduces a new ksu-modsys-overlay implementation that provides the default overlay-based module system
• Refactors ksud to delegate module operations through a transparent forwarding interface

The condition (caps.get(1), caps.get(2)) != (None, None) is redundant since captures() already ensures capture groups exist. This condition will always be true when captures() succeeds.

Suggested change

	if let Some(caps) = re.captures(s)
	&& (caps.get(1), caps.get(2)) != (None, None)
	{
	if let Some(caps) = re.captures(s) {

The subcmd should differentiate between 'type_change' and 'type_member' operations but is hardcoded to 0, potentially causing incorrect policy handling.
