fix(mc): resolve JVM GC conflict — disable Aikar flags, use ZGC#9895
Conversation
Aikar flags set G1GC + JVM_XX_OPTS set ZGC = "Multiple garbage collectors selected" crash on startup. Disable Aikar flags and use ZGC with generational mode + tuning flags instead.

- Set ONLINE_MODE=false in e2e container — no Mojang auth needed - Add early JVM GC conflict detection in wait loop — fails fast instead of waiting 300s for a server that will never start - Enable has_test: true + e2e_name in mc.mdx so CI runs e2e before publishing, preventing broken images from reaching production
