Pull request overview

Adds a “late-load” mode so KernelSU can be loaded and initialized after Android has fully booted (primarily for LKM workflows), and documents how modules/scripts behave in that mode.

Changes:

• Add ksud late-load command to load kernelsu.ko from embedded assets (by KMI) and run late-load + normal module stages.
• Extend kernel/userspace signaling for late-load via get_info().flags (0x4) and expose it to scripts via KSU_LATE_LOAD=1.
• Document late-load behavior and script ordering across multiple website locales.
