The mechanism, read off the instruction stream rather than fitted: Mars_Vec3_Normalize
(0x00422520, 123 callers) narrows to float32 four separate times, and MoveFleet stores
each dest.c - pos.c back to a float32 slot before calling it and takes the leg distance
from that same call's return value. Live 8/45 -> 0/45 with a control run of the unchanged
build, identical inputs and identical original outputs on all 45 calls.
Board: the two MoveFleet rows go verified; VM140 exclusivity back to FREE with two new
click-path gotchas; a new backlog row for waypoint types 2-5, which this lane attempted
and could not reach - ref-turn2 structurally cannot produce a node-line move because the
only player that would travel one has no ships.
(Most of this lane's files were swept into 9d385a7 by another lane's `git add -A` on the
shared repo; this commit carries what was left.)
