v0.9.0

Two import-only breaking changes — the vortex-core types moved under io.github.dfa1.vortex.core.*, and the no-arg DType factories became constants. In return, Vortex now ships with no FlatBuffers or Protobuf runtime dependency: the .fbs/.proto schemas compile in-house to MemorySegment-native Java, dropping com.google.flatbuffers:flatbuffers-java — the last automatic-module dependency — so a named JPMS module-info is viable, and the generated wire classes are prefixed so they no longer collide on your classpath (ADR 0017).

Added

• Canonical non-nullable DType constants: DType.I8 … I64, U8 … U64, F16/F32/F64, plus BOOL, UTF8, BINARY, NULL, VARIANT; build a nullable column with DType.I64.asNullable(). (f4b22e42)

Changed

• Breaking (imports): every vortex-core type moved under io.github.dfa1.vortex.core.* — core.model (DType, PType, TimeUnit, EncodingId, ExtensionId, Time*Dtype), core.io (IoBounds, PTypeIO, VortexFormat), core.error (VortexException), core.compute (FastLanes, PrimitiveArrays), core.fbs/core.proto (wire codecs). E.g. io.github.dfa1.vortex.core.DType → io.github.dfa1.vortex.core.model.DType. (52f30c16)
• Dropped the com.google.flatbuffers:flatbuffers-java runtime dependency; the .fbs/.proto schemas compile in-house to MemorySegment-native Java, and the generated wire classes are prefixed Fbs*/Proto* so the generic names (Array, Buffer, DType, …) no longer collide on your classpath (ADR 0017). (5907302e)

Removed

• Breaking (imports): the no-arg DType factories (DType.i64(), DType.utf8(), …) — use the constants above (DType.i64() → DType.I64). DType.decimal(..)/DType.structBuilder() and the record constructors are unchanged. (f4b22e42)
