[1.0.1] - 2026-11-06

Updated odin-xitdb native engine submodule to b760ee9 (lock-free stateless positional cursors, vmem-backed Core_Memory, reverse and upper-bound range iterators across all collections, and empty-collection iterator root-read skip optimization).

Initial release of Xitdb Elixir client wrapping odin-xitdb via a C-ABI Erlang NIF (priv/xitdb_nif.so).
Lazy 9-byte Slot cursor (%Xitdb.Cursor{}) implementing Access, Enumerable ($O(1)$ count/1, $O(1)$ member?/2, $O(\log N)$ slice/2, chunked reduce/3), and Inspect.
Coarse-grained transactions (Xitdb.transact/3) supporting both nested Elixir maps/collections and put_in/3 / update_in/3 / pop_in/2 cursor pipelines.
Time-travel snapshots (Xitdb.db/1, Xitdb.as_of/2), structural diffs (Xitdb.diff_moments/3), and attribute lineage (Xitdb.history_of/2).
Compile-time validated selector (~x) and Datalog (~q) sigils, Datomic-style Xitdb.pull/2 projections, and Datalog queries (Xitdb.query/3) with B+Tree secondary index pushdown and grouped aggregations.
Spark DSL extension (Xitdb.Ash.Resource), introspection (Xitdb.Ash.Info), transformer (Xitdb.Ash.Transformers.WireChanges), verifier (Xitdb.Ash.Verifiers.VerifySyncProjection), and declarative transaction macros (Xitdb.Ash.Tx.tx_for, tx_for!).
4-layer Client ATDD executable specification suite (test/features/*_spec.exs) and StreamData property tests.
1v1 Client Statistical Benchmark Suite (benchmarks/) comparing the Elixir NIF wrapper against Raw Odin across 16 client workloads.
