Replaces the old vendored BDK with the one from hekate v6.5.5 (CTCaer's 2025/2026 refactors: sdmmc, SE, minerva v1.6, display, heap, return value homogenisation). OmniNX additions re-applied on top: bq24193_charger_connected() and jc_clear_input(); s_vprintf now ships with the BDK. Ported to the new API: - sd_mount(), sdmmc_storage_* and ini_parse() now return 0 on success. The installer checked ini_parse() != 1, which would have made it miss manifest.ini and run every install as a clean install. - SD helpers come from bdk/storage/sd.c (source/nx_sd.* removed), ffsystem.c from the BDK, diskio.c/ffconf.h from hekate (ffconf keeps the sd:/ volume prefix). - minerva_init() needs the minerva storage; the installer still drops to 800 MHz afterwards. - Payload launch follows hekate (sd_file_read, hw_deinit); coreboot path removed upstream. - Stack moved to 0x96000000: the old 0x83100000 is inside the new heap. - GUI/USB/compression parts of the BDK are not built.
