Containment Frontier 0.5.0-beta.4

Clean installation update for Minecraft 1.21.1, NeoForge 21.1.265 and Java 21.

• Removes the forced Turkish language option. The pack no longer supplies a Minecraft language selection or a saved pack-language preference. Pack-owned interface and quests initialize from the selected Minecraft language when supported, with English fallback; the Operations Language setting remains available independently.
• The world list starts empty. Create a new Survival world with Hardcore disabled; the campaign installs its authored theater automatically from the included map resources.
• Includes a matching Docker Server Pack as an additional file. Read its README for setup, networking and backups. Use matching client/server versions.
• Retains the approved campaign module, pinned mods, six pack-owned languages, visual defaults, quests and campaign map resources from Beta 3. Item and block names remain English where the pack's existing language scope requires it.

Import into a separate profile. Do not delete or overwrite existing worlds; keep independent backups before updating. The language change does not migrate a preference already saved in an existing profile.

The exact unchanged campaign module passes 197 Java test programs. Release checks cover dependency and payload parity, clean installation defaults, archive integrity and secrets. These checks do not claim a new complete survival playthrough or exhaustive multiplayer/performance qualification. Full earned campaign completion and long-session playtesting remain open beta work.
