Resolves #643 (Part 4).

Summary of Changes

1. **Extract **:

   • Extracted layout tracking, node collections (patternNodes, patternSelectNodes, queryNodes, querySelectNodes, bindingNodes, constructNodes, argList), and index allocation (allocateNodeIndex, allocateEdgeIndex) out of Query.java into a dedicated, cohesive VariableLayout.java component.
   • Preserves filtering semantics for non-variable and blank nodes.

2. Rename Engine Query to QueryPlan:

   • Renamed fr.inria.corese.core.next.query.impl.engine.pattern.Query to QueryPlan.
   • Completely eliminates the pervasive naming collision with the public contract fr.inria.corese.core.next.query.api.Query.
   • Updated references across engine evaluation, solution management, diagnostics, query planning, SPARQL compilers, and test suites.

3. Validation & Quality:

   • Added comprehensive unit tests in VariableLayoutTest.java with 100% coverage of layout operations.
   • SonarLint scan: 0 alerts across all modified and created classes.
   • Architectural boundary enforcement verified via NextModuleBoundaryTest.
   • All repository tests (4,880+ test cases) pass cleanly.
