re: bounded scan fixes the freeze; mission-over branch confirmed on the oracle

Browse Source 
Bounding the pointer scan to 0xBC000000-0xBD000000 (with a full-sweep fallback)
drops find_mission from a ~371MB walk to 0.7s. The run then went 694s with the
probe attached and NO freeze, against 3-of-3 frozen inside ~4 minutes with the
unbounded version. n=1, but the first probe-attached run to survive.

State encoding pinned to three points: 1 = not yet deployed, 2 = active,
4 = destroyed. ADN111 caught going 2 -> 4 at 433s while the active count fell
36 -> 27.

The phase ended at 694.9s WITHOUT the ordinal advancing, and every field matches
the branch read statically from sub_82260710: [phase+300]=2 (last-phase flag),
[mission+20]=0 (mission-over state), [phase+196]=1 (finished), [mission+40]=1
(unchanged). The static state machine is confirmed on the live oracle for the
mission-over half.

But this was a LOSS, not a clear: GAME OVER on screen, escort at 35.7%, pilot
DEAD at 676s, and two of the three objective squadrons still at state 2. So the
'destroy all three clears phase 1' prediction remains untested. What is
established is that the else-branch is the only route to phase 2 and needs
[phase+300] != 2 when the phase ends.

Five attempts, still no phase advance observed -- the obstacle is now keeping the
escort alive, not the freeze or the instrument.
