Drew T 8ffb7f0607 feat(phase-7): -O0 split + 4 matches (42 real) + libcd.h — session B checkpoint ...

- per-file -O0 mechanism: split text c-subseg into boot@-O0 (src/boot.c) + 800@-O2
  via splat resegmentation + Makefile target-specific CC1FLAGS; the boot/main/
  game-mode-dispatch module (0x80010000-0x800123F0) is -O0, not the pinned -O2
  (per-module compiler mixing, SETUP §5.5). Regression-gated byte-identical.
- 4 byte-matches (38->42 real, make check BYTE-IDENTICAL throughout): GameModeDispatch
  (-O0 register-ptr far member), DebugMenuHandler (-O0 reserved-slot local), CdQueueBusy
  (-O2 if/else order + branch polarity), CdReadRequest (-O2 early-return fall-through)
- PsyQ infra: include/psyq/libcd.h (CdlLOC/CdlFILE from the .gdt) + 4 named symbols
  (CdSearchFile/CdPosToInt/CdIntToPos/VSync) in symbols.us.txt; func_* stubs renamed
- loader cluster non-jtbl COMPLETE (6 matched + 2 drafted): NON_MATCHING drafts of
  LoaderInitFileTable + ResourceLoadStateMachine (logically faithful, residuals in-source)
- tooling: progress.py/difficulty.py fixed for the multi-file split (glob src/*.c, all
  asm dirs, skip forward-decls); deterministic; 42 real / 4 NM
- flywheel: matching-cookbook §6 (-O0 detection + idioms), §7 (PsyQ types/symbols), T4
- build byte-identical 143dbb89f34491258bbc27810d0a12ec8b43a8dd from a full clean cycle
