feat(config): -O0 whale carve step 1 — split 0x80144B9C..0x801458E0 out of ov_MAIN_012_jr_8013F350

o0_subsplit: 2 unmatched stubs (func_80144B9C 770 ins + func_801457A4 79 ins), 0
already-matched islands interleaved, so K=0 and one -O0 region is correct. carve
repoints (none); config/overlays.mk UNCHANGED (the whale object owns no .rodata
carve anywhere in the fleet: 0 of 213 splat yamls carve .rodata to an _o0b).

BYTE-NEUTRAL, which is the whole claim of a carve:
  build d6b3e8b971cdd6c53aea8c4f265afb82b363283c == config/check.ov_MAIN_012.sha
interleave_check ALIGNED. Derived AND carved under .run/auto/gate.ov_MAIN_012.lock
(the commit:2791 rule: a plan derived outside the lock can describe a tree state that
never existed).
