Create Connected World v3.1

Changes from v3:

• Add Sleep Time Simulation 0.4.4-neoforge.1 for Minecraft 1.21.1 to both client and server. Accelerates world simulation during sleep while retaining normal-rate mob movement; client adds the progress overlay.
• Include JEI 19.51.0.418 on the server (already present in the client manifest).
• Include the prior server TrashSlot correction.
• Set default client render distance to 10, simulation distance to 8, entity distance to 75 percent, and dynamic lights to FAST.
• Disable Better Leaves in the default enabled-resource-pack list; keep its catalog entry available.
• Add medium-based Complementary r5.9.3 presets with 96-block shadows, including Euphoria variants. Preserve the existing shader selection and shaders-off default.
• Enable an eight-model solid-render-layer Lootr barrel compatibility patch. Candidate fix; needs a visual check on the affected laptop. Loot, block identities and opened/unopened textures are preserved.
• Preserve all 297 existing catalog entries and the v3 recipe-priority patch.

No world reset, structure-density change or villager change. Existing worlds and server settings are not bundled.

Validation: ZIP integrity, manifest consistency, duplicate/path checks, matching sleep jars and recipe preservation. Sleep behavior passed dedicated-server simulated-player testing; client visual/FPS testing and a fresh CurseForge import of these exact archives remain pending. These archives have not been submitted to CurseForge moderation. The author's new NeoForge sleep build is included as a mod override, not an existing CurseForge file reference.
