…er options - Rename AbstractNTriplesNQuadsListener to dedicated NTriplesQuadsTermDecoder - Remove obsolete reflection and deprecated adapters in serializer test fixtures - Clean up serialization options and literal temporal value representations
…M debt - Remove obsolete KGRAM artifacts: Type.PATH, initPath, clean, min/max bounds, isGraphPath - Strip unused query path flags (isCheckLoop, isListPath, isStorePath, isCachePath, isCountPath) and pathFilter - Unify SPARQL execution pipeline with SparqlQueryExecutor, SparqlUpdateExecutor, and AstBackedFilter - Add immutable compiled query plans with cache, top-k selection, and progressive streaming evaluation - Expand execution diagnostics and memory storage snapshot query isolation tests Resolves #617
…stics documentation - Enforce isolated native classpath and -Werror in build.gradle.kts - Update architectural boundary tests in NextModuleBoundaryTest - Document streaming SELECT, Top-K ordering, plan caching, and execution diagnostics

Summary
This PR cleans up, modernizes, and consolidates the native query engine in
core.next, eliminating historical KGRAM baggage and unifying execution on top of immutable query plans, progressive streaming SELECT, and clean boundary architecture.Resolves #617
