First NeoForge 1.21.1 release

This is the first 1.21.1 NeoForge build, ported from the 1.20.1 Forge branch with identical features. Marked beta: the server boots and loads cleanly, but the client GUI, HUD, teleport and group editing have not been play-tested on 1.21.1 yet.

Added

• Pinyin search for mobs — the mob tab now matches Chinese names and pinyin, the same way the biome and structure tabs already did.
• Custom groups — sort known locations and saved mobs into your own groups, plus a one-click "add current position" button.
• Teleport button — jump straight to a search result (works across dimensions).
• Optional BiomeSpy support — with BiomeSpy installed, biome search takes the vanilla findClosestBiome3d path that BiomeSpy accelerates.

Fixed

• Known locations now follow the client language instead of always showing the English ID.
• Structure search no longer blocks the server thread — it always runs on the background worker with a tick budget and a timeout.
• Client-side 120s fallback, so the HUD can no longer sit on "searching" when the server never answers.

Notes

• Teleport defaults to off on this branch (allowTeleport=false): a cross-dimension teleport for every player is too much to enable by default on a new platform. Turn it on in the config if you want the button.
• Requires NeoForge 21.1.235 or newer on Minecraft 1.21.1.
