Oracles reference shared helper oracles (heightmap, level shape...) that
javac could not find when only the entry files were listed. Also let
chunkgen_bench list unsupported features (HORIZON_LIST_UNSUPPORTED=1).

VanillaLevelShapeOracle evaluates BlockState.updateShape and canSurvive over
generated 5x5x5 neighbourhoods with a reflective LevelReader and records the
ticks requested through ScheduledTickAccess; level_shape_fixture does the same
through Behaviours. 40000/40000 random cases match. Walls, snow layers and sea
pickles now read position-dependent collision shapes (bamboo, speleothems,
shulker boxes) through DynamicSupport.
