Add negative game tests for all advancements

[Copilot]

Adds negative game tests for all advancements to guard against false-positive triggers, mirroring the pattern from CyclopsMC/IntegratedDynamics#1620.

Changes

• assertAdvancementNotDone — new helper symmetric with assertAdvancementDone; asserts an advancement was not obtained
• root negative — triggers inventory_changed with DIRT instead of minecraft:chest
• uncolossal negative — places a vanilla CHEST instead of uncolossal_chest
• base/* negatives (×7) — forms a chest with the wrong material (e.g. form COPPER, assert base/wood not done)
• size/* negatives (×7) — forms a chest of the correct material but size 2 (below the required ≥10 threshold)

// Example: size advancement should NOT fire for a small chest
@GameTest(template = TEMPLATE_EMPTY)
public void testAdvancementSizeWoodNegative(GameTestHelper helper) {
    testAdvancementSizeNegative(helper, ChestMaterial.WOOD, "colossalchests:size/wood");
}

private void testAdvancementSizeNegative(GameTestHelper helper, ChestMaterial material, String advancementId) {
    BlockPos excludedWall = POS.offset(1, 0, 0);
    createChest(helper, POS, material, 2, Sets.newHashSet(excludedWall)); // size 2, not ≥10
    ServerPlayer serverPlayer = makeMockServerPlayer(helper);
    placeBlockAsServerPlayer(helper, serverPlayer, excludedWall, material.getBlockWall());

    helper.succeedWhen(() -> assertAdvancementNotDone(helper, serverPlayer, ResourceLocation.parse(advancementId)));
}

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• maven.fabricmc.net
  • Triggering command: /opt/hostedtoolcache/Java_Microsoft_jdk/21.0.2/x64/bin/java /opt/hostedtoolcache/Java_Microsoft_jdk/21.0.2/x64/bin/java --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.lang.invoke=ALL-UNNAMED --add-opens=java.prefs/java.util.prefs=ALL-UNNAMED --add-opens=java.base/java.nio.charset=ALL-UNNAMED --add-opens=java.base/java.net=ALL-UNNAMED --add-opens=java.base/java.util.concurrent.atomic=ALL-UNNAMED -Xmx3G -Dfile.encoding=UTF-8 -Duser.country -Duser.language=en -Duser.variant -cp /home/REDACTED/.gradle/wrapper/dists/gradle-8.8-bin/dl7vupf4psengwqhwktix4v1/gradle-8.8/lib/gradle-launcher-8.8.jar -javaagent:/home/REDACTED/.gradle/wrapper/dists/gradle-8.8-bin/dl7vupf4psengwqhwktix4v1/gradle-8.8/lib/agents/gradle-instrumentation-agent-8.8.jar org.gradle.launcher.daemon.bootstrap.GradleDaemon 8.8 (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
