PBP: the frontend's IsDiscPath never accepted .pbp (kind=none, 'Invalid launch request.'), pbp_read_sector returned 0-on-success against the TS_* convention, and the reader indexed image blocks with the core's 150-based disc LBA. Tracks now live in absolute LBA space like cue/chd, reads return real TS types, the subchannel polarity matches chd, and zipped PBPs rank as launch candidates. Crash chains from the Samsung tombstone: device create()s are calloc'd so a failed psx_init no longer makes psx_destroy free garbage; psx_disc_create and the raw-disc malloc are NULL-checked; queue_destroy tolerates NULL; a shutdown requested between runs is dropped at run() entry instead of killing the next session on frame 1; its SDL_QUIT push is gated on a live loop (the event-queue mutex may be destroyed between sessions) and a stale queued quit is flushed before the loop starts. Also: disc-probe gate links again (psx/perf.c was missing from its sources).
