* Rewrote mutex handling throughout the code to use a small, macro-based scoped lock implementation. * Removed extern variables from common.h - launch path management is now completely handled in utils.c. * Updated NpdmSystemCallId_Count to reflect changes introduced in 12.0.0. * Added NcaMainSignatureKeyGeneration enum. * NCA main signature moduli are now retrieved from FS .rodata at runtime. * Simplified lock management in usb.c by using a single global mutex with scoped locks instead of three different r/w locks. * Updated FatFs to R0.14b. * Enabled 64-bit LBA support in FatFs to potentially support custom eMMC replacements / resized USER partitions in the future. * Updated LZ4 to v1.9.3. * Fixed typos. * USB gamecard dumper PoC now only dumps the Initial Data area. * Updated to-do list.
