#119-residual: [viewer] capture probe - the capture half of the tower capture-replay loop

Browse source 
One line per change of (root cell, flood size, OutsideView polys, player
cell), with the projection eye at mm precision on every line
(ACDREAM_PROBE_VIEWER=1, print-on-change, silent while stable). The
tower-ascent harness replays the captured production (eye, root) pairs
deterministically - replacing the synthetic helix that proved unphysical
in the roof-lip band (the real collided camera may never reach it).

Suites: App 238+1skip, Core 1422+2skip, UI 420, Net 294.
