Summary

GotA target acquisition checks visibility even for enemies that cannot beat the current nearest target. Moving the read-only visibility lookup after the existing distance and tie predicate skips those unnecessary lookups in footman and hero acquisition. Scan order, tie rules, and target updates stay unchanged.

Manual Tests

• Eight paired full matches used BASIC and neural rosters across four match/map seed combinations. Both variants used the same pinned Nim/GCC release build; each pair ran in the same container, with execution order alternating by seed.
• All eight pairs produced byte-identical replays and equal parsed results. Median native wall-time savings were 1.00% (103 ms), ranging from 0.31% to 1.43%. This is a small effect with one pair per configuration.
• Measurements used release source 02eda3d; the target-selection source and dependencies are unchanged on this PR's base 179603b.
