claude-re 91fb022caf re-capture: a dead display must not look like a playing movie
skip_intro.sh compared two screenshots to detect the intro movie. When the X
server died 3 min into a run, `screenshot` failed silently and left both PNGs
at their previous contents — two stale files, whose RMSE is a constant non-zero
number, i.e. exactly the signature of a changing screen. The loop then reported
"movie -> skip A" every 5 s for the whole 600 s timeout with no emulator and no
display alive, and the session wasted 10 minutes before saying BOOT FAILED.

Both waiters now verify, every iteration, that the screenshot was actually
written, that the display answers xdpyinfo, and that a non-zombie xenia_canary
exists — with distinct exit codes (3 display, 4 emulator, 5 capture) so the
session log names the cause instead of timing out.

Also adds mission_state.py + escort_session.sh: read pos+0x154 against each
definition's HP for EVERY entity, to test whether the hull anchor is a property
of the entity class rather than of the player object (the escort question).

# Wait until the game is actually FLYING, then return — do not guess with sleeps.
#
# `launch_mission.sh` used to allow a fixed 75 s for the launch cinematic, the
# stage load and the objective card. Under lavapipe that is not a constant: one
# run needed 75 s, the next was still in Raymond's dialogue at 140 s, so the A
# meant for the OBJECTIVE card was swallowed by the cutscene and the card sat
# there forever.
#
# The in-flight HUD is unmistakable: the SHIELD bar is a solid bright green
# block at the bottom of the screen, and no cutscene or menu has anything green
# there. So poll that pixel, and tap A every few seconds until it appears (which
# dismisses the objective card whenever it happens to be up).
#
# Same liveness rule as skip_intro.sh, for the same reason: a failed screenshot
# leaves r/g/b unset, they default to 0, the green test fails, and waiting for
# the HUD becomes indistinguishable from waiting for a dead emulator.
