Add libksud support and KMI selection

Add support for KernelSU packages distributed as libksud.so and allow choosing KMI/arch from the UI. Changes include:

- Introduce Global.KSU_KMI to override detected KMI.
- Add Libksud parser (Libksud.cs) to scan embedded zlib assets, parse rust-embed index, recover asset names and export ksuinit/kernelsu.ko.
- Update KernelSUPatch to locate libksud.so, use Libksud to extract the correct kernelsu.ko for the selected KMI and ksuinit, then inject them into the ramdisk.
- Update PatchDetect to search for "*libksud.so" and treat it as LKM mode (useful), instead of failing.
- Extend BasicflashView to asynchronously populate arch/KMI list from libksud assets, refresh UI bindings, and set Global.KSU_KMI from the selected item.
- Add extract_and_verify.py: a standalone Python helper to extract assets from libksud.so, optionally download KernelSU release assets and verify hashes.

Also includes heuristics/improvements for asset name recovery when rust-embed parsing fails, and various UI binding/refresh fixes.
