Auroral 1.1.1

A compatibility and polish update. The aurora now renders correctly under Iris and Sodium with shader packs, and the start sound is quieter and no longer repeats during the same night.

Fixed

• Aurora rendering with shader packs. With Iris, Sodium, and a shader pack such as Complementary installed, the aurora was breaking into visible triangle facets across the sky instead of glowing smoothly. The ribbon now blends correctly through any shader pack's atmospheric pipeline.
• Aurora start sound. Now plays on the weather sound channel at 30% volume and only once per night. Previously the sound was at full volume on the ambient channel and could replay if a Hearthwood Log and Aurora Shard forced a second aurora during the same night.

Changed

• Minimum NeoForge version. Auroral now requires NeoForge 21.1.215 or newer.
