Ultra Fast Pregen

## Ultra Fast Pregen 14 for Forge 1.20.1 Requires Forge 47.x, Minecraft 1.20.1, Java 17+. Server side only (works in singleplayer). ### Faster * **Worldgen-heavy worlds:** feature placement skips Minecraft's per-call chunk checks inside a batch, and `matching_blocks` predicates compare blocks directly (Tectonic + WWOO + C2ME: 127.8 → 156.8 chunks/s, measured on NeoForge 26.1.2). * **No more waiting for the previous batch's lighting:** the batch's last tasks go first (with C2ME: 354.2 → 378.1 chunks/s, measured on NeoForge 26.1.2). * **Modpacks keep the fast terrain path:** the check of other mods' mixins now looks at the methods they actually change, so mixins that only add accessors or touch other methods no longer slow it down. ### Safer * **Safety net:** if a batch fails on the fast paths (usually another mod's code that does not expect them), it is generated again the way Minecraft does and the run carries on; the log names the mods involved. Before, the run stopped. * Fixed a server crash at start-up with **FastChunkGen**. * Fixed "reading the area's region headers failed" with **FastChunkGen**'s chunk storage. * Lighting can no longer hang: a batch whose light makes no progress for 3 minutes stops with a message. ### Speed Against Chunky on NeoForge 26.1.2 (Ryzen 5 7500F, 3,000 × 3,000 blocks): Overworld 3.1×, Tectonic + WWOO 5.3×, Nether 4.2×, End 1.4× faster; 1.1× to 1.6× with C2ME on both sides. Full numbers on the project page. ### Tested on this build * The automated test suite passes: blocks, biomes and light identical to Minecraft's own generation (Overworld, Nether, End and the other world presets), batch edges, stopping and resuming, joining existing areas, and the safety net. * On a dedicated server, in the Overworld, Nether and End with every saved chunk checked, alone and together: Canary; Canary, Noisium, FerriteCore, ModernFix; Distant Horizons; Terralith, Biomes O' Plenty, Alex's Caves; all of them together, plus YUNG's Better Caves. All passed. * Modpack All the Mods 9 1.1.1: 4,096 chunks in 1 min 59 s (34.3 chunks/s) on the fast terrain path.
