SUPERSEDED: Custom Projectiles 1.8.10 target-priority experiment

SUPERSEDED FOR TARGET PRIORITIES. Do not use this 1.8.10 tester ZIP as evidence that Custom Projectiles configures the game's native threat/distance targeting. Use the 1.8.9 provisional tester for the current baseline.

The 1.8.10 threat_priority experiment ranked unit types before distance inside the module's separate automatic unit scan. Research of UnitsState::acquireShootTarget found a native selection policy that combines distance, target attention, shooter/target type, range and obstruction. The experiment did not configure that native policy and was reverted in source PR #12. Store draft #31 is pinned back to 1.8.9.

The assets here are retained only to identify prior tester results; their checksums and source provenance remain unchanged. A corrected native-integrated targeting option is open under issue #10. Neither this artifact nor the 1.8.9 baseline is a gameplay-accepted final release.
