ci: recalibrate §F size budget to 180 KB (table ~55 KB + legacy narrative ~110 KB)

The 150 KB threshold assumed the §F region was table-only, but it also
holds ~92 KB of pre-ctx-opt D24–D33 bullet narrative plus the M-111/M-113
write-ups. The regression signal is fat ROWS re-accumulating (table is now
~55 KB), so the budget sits ~15 KB above today's 166 KB total.
