[review] Movement/pathfinding parity failures due to turn depletion

[rdearman]

Summary

Movement/pathfinding parity failures due to turn depletion

Evidence / Details

Many failures are 1308 out of turns; ensure tests grant enough turns or reduce path batch; separately validate genuine 1406 path-not-found cases.

Expected outcome

• For repair: fix implemented and tests.v2/ regression test passes.
• For review: root cause + decision documented (may end in “expected behaviour”).
