🚀 v2.3 - Robustness & Improved Root Support 🚀

This release focuses on improving stability for older architectures, ensuring compatibility with the latest KernelSU interfaces.

KernelSU Supercall Support: Implemented the new ioctl-based supercall interface for KernelSU (v20000+). This replaces the deprecated prctl method, ensuring compatibility with the latest KernelSU versions.
Relaxed Version Checks: Version limits for KernelSU have been relaxed to support community variants, with warnings now issued in logs instead of strict enforcement.

Direct FD Passing: Migrated mount namespace transfers to use Unix domain sockets (SCM_RIGHTS). This resolves "Permission denied" errors (Errno 13) encountered on certain Android 12 (arm32) devices when accessing namespace paths via /proc.
Ptrace Fallback Mechanism: Introduced a fallback to PTRACE_ATTACH for kernels where PTRACE_SEIZE fails with an I/O error. This includes robust signal handling to ignore spurious "noise" signals during the injection process.
Legacy Register Support: Added support for PTRACE_GETREGS and PTRACE_SETREGS for 32-bit ARM devices that do not support modern regset interfaces.
Path Correction: Fixed the executable path for the 32-bit Zygote to correctly point to /system/bin/app_process32.

Socket Communication Fix: Resolved a critical buffer overwrite bug in recv_fds where control message validation was failing due to dummy data corruption.
Improved Fossil Detection: Enhanced the detection of suspicious "zygote fossils" by monitoring loop device mounts, improving the stealth and cleanliness of the environment.
FD Sealing: The daemon now gracefully ignores errors when adding seals to module file descriptors, improving compatibility with older or custom kernels that lack full sealing support.
Protocol Synchronization: Added status byte checks to the communication protocol to prevent stream desynchronization during namespace transfers.
