Faster green test suite

- Removed the core processResources skip that fired on test-only invocations, which packaged a core jar with no generation kernel catalog and made all 10 probe and bukkit-plugin tests that reach GenerationKernelRegistry fail on every ./gradlew test
- Set maxParallelForks on :core:test to half the available processors, overridable with -PtestForks, and left the small modules single-forked so they do not re-pay the Minecraft bootstrap per fork or steal worker leases from core
- Resolved B.registries() per bound platform instead of latching the first one for the JVM lifetime, keeping the previous unbound behaviour, so a test that binds its own platform no longer reads a foreign platform's block states
- Resolved IrisObject.States per bound platform through accessors instead of static finals fixed at class-init, removing the NoClassDefFoundError and null material-key failures that appeared whenever class partitioning changed
- Bound an explicit platform in EngineMantleCoverageTest and IrisDimensionStackActuatorMetadataTest so they no longer depend on another class leaking a binding first
- Gated BukkitSpiConformanceTest registry probes on a live RegistryAccess and restored the IrisPlatforms binding it leaked, which was silently swallowing the stderr two SettingsHotloadWatchTest assertions read
- Initialised org.bukkit.Registry and Biome inside the RegistryAccess mock scope in ObjectStudioGeometryTest so Mockito no longer instruments Registry mid-clinit
- Replaced the SettingsHotloadWatchTest fixed 1200ms diagnostic window with a 10ms condition poll bounded at 4s
- Replaced the IrisCaveCarver3DNearParityTest wall-clock speedup benchmark with a deterministic density-sample count, cutting 28 carves to 2
- Cut HydrologyPlannerTest cold-owner parity from 12 tile plans to 4 and shared the immutable baseline plan across the early-owner tests
- Built one prototype project or staged history per class in the jigsaw studio and world replacement tests and copied it per test, replacing repeated fsync-bound fixture construction
- Replaced Mockito block-state fixtures with concrete implementations in the object IO, deposit modifier and nearest-block-index tests, removing about 2.5 million interceptions
- Replaced Thread.sleep with bounded condition polling in HydrologyTileCacheTest
- Deleted 19 test classes and 60 further test methods that asserted on production .java source text rather than behaviour, and removed the 19 now-unread iris.*Source system properties that fed them
