#118 correction sweep: the ARCADE's eject was LIVE -- 'dead code in 4.10' was wrong

The absolute-pointer scan missed the E8-relative call; the later byte-scan
found it (FUN_004a9b5c+0x10 -- the master performance evaluates eject
permission per frame in the shipped binary). Under deadline pressure the
disproven 'unfinished/dead code' claim leaked back into three comments and
the handoff; swept per the correction mandate.

Settled press model, now stated correctly everywhere: pilot eject = the
pilot KEYPAD bank while armed (+ the PANIC key reporting through that
matrix). The MFD soft keys NEVER pilot-eject in the binary -- every page
routes them to authored functions; the flashing engEject cell is the
INVITE LAMP. The port's page-gated eng-key eject is a MARKED CONVENIENCE
deviation (operator-requested), and the coolant hysteresis is a MARKED
smoothing deviation for a degenerate boundary oscillation -- not
completions of unfinished code.
