- Re-inject persistent dimensions from the levels-ready hook before the watchdog starts

- Add the 1.21.1 data version and datapack supported_formats range
- Cascade regions whose sea or shore pool loses every biome
- Use Gson calls available on the 1.21.1 runtime
- /locate biome on non-stacked Iris dimensions searches the visible biomes chunks are filled with instead of falling back to the vanilla structure-biome search
- BiomeSearchFilter rejects columns whose region, land, sea, shore, cave, carving, subterrain or image-map biomes cannot hold a target, so terrain height is computed only for columns that can match
- Hydrology planning state is consulted only when a target comes from a river policy, so a locate no longer queues hydrology tile plans across its whole radius
- Admitted samples resolve inside their generation-history coordinate scope, so saved-biome reads for generated chunks no longer fail the command
- HintedLocator surface hints and IrisBiome visible key enumeration are shared with the locate filter
- Bukkit and modded biome policies share the same filtered search
- Saved Iris dimensions are prepared in parallel during world load (server-about-to-start on NeoForge and Forge, server-starting on Fabric), before the server watchdog runs
- Server start only creates the restored levels, builds their engines in parallel, and publishes them, so its wait no longer grows one world at a time
- Each restored dimension opens its generation history once instead of twice and resolves its active pack once instead of three times
- An epoch snapshot whose content matches its validated source pack reuses that validation instead of running the full pack validator for every world
- Level creation reads the configured pack and structure biome keys from data warmed during preparation
- Immutable generation packs feed the prepared hydrology cache identity from the data's memoized fingerprint instead of hashing the pack twice per engine build
- Restore logging reports each dimension's preparation and engine time and how long the server thread waited
- Themed regions, those at least five times rarer than the dimension's median region, no longer receive adopted biomes while a common region accepts the biome's role
- Themed regions still take a mod biome when no common region has a pool for its role or every common template is full
- Category affinity now chooses among common regions, so a rare biome is no longer locked inside a region that can be absent for thousands of blocks
- Each pack biome now serves as the template for at most five adopted land biomes and three adopted sea, shore, or cave biomes
- A mod biome whose best template is full falls back to the next best template under the cap
- A mod biome that finds every compatible template full is skipped with a reason naming the cap instead of being dropped
- Converted patch decorators also lose the share of surface columns that earlier surface patches in the declaring biomes already occupy, estimated from those patches' expected coverage in the catalog
- Canopy and surface occupancy are combined into one vegetation occlusion estimate per decorated feature
- For land biomes with known categories, the region climate tie-breaker averages only the region's templates that share a category with the mod biome, so a mixed region no longer looks temperate on average
- A small region affinity term favors regions whose templates share the mod biome's categories
- A mod biome that brings its own vegetation pays a template penalty scaled by the share of the template's top surface layer that cannot hold plants, so snow, ice, sand, and stone templates no longer swallow its trees
- The top layer palette is resolved through biome-palette snippets and weighted by palette entry weight
- Mod biomes without their own vegetation keep the closest climate template
- Ores declared only by adopted cave biomes are written to the deposits of the region each cave biome joined, scoped to those cave biomes, instead of to the cave biome itself where the deposit stage never reads them
- Ores of adopted surface biomes still go to the biome
- The worldgen catalog (format 2) records the members of every block tag referenced by a captured placed feature, so ore targets using mod block tags convert instead of passing through
- Ore conversion supports noise_based_count and noise_threshold_count placement counts
- Converted ores that produce another converted ore's host block are written ahead of it, so an ore whose host comes from a sibling ore finds that host during the deposit stage
