Fuaran.UI.OpStream.Dag.Sqlite

Microsoft.Data.Sqlite-backed implementation of IDagOpStreamSink<'Msg> (from Fuaran.UI.OpStream.Dag.Abstractions).

The durable counterpart of the in-memory DAG sink. Records live in a dag_op_record table keyed by (stream_id, hash); the trunk head lives in a dag_head table. The TryAdvanceHead compare-and-swap is a conditional UPDATE dag_head SET head = @new WHERE stream_id = @s AND head = @expected — atomic at the statement level, so two racing advancers from the same expected head leave exactly one winner. The genesis advance (expected = None) is an INSERT … ON CONFLICT DO NOTHING whose rows-affected distinguishes "head unset" from "head already set".

Add is idempotent by content address; a hash collision with differing content is rejected. Topology queries (Parents / Reachable / Lca) load the stream's (hash, parents) rows and delegate to the pure DagTopology algorithms. Tombstone drops the op payload (op_json reset to an empty batch, outcome_hash cleared, tombstoned = 1) while preserving the hash + parent links, so the chain stays verifiable.

Opt-in (rung-4): a consumer that never references the DAG packages pulls none of this.
