Module binder 

Binder — lowers an AstQuery to a GraphPlan.

The binder is the stage between the parser and the execution engine. It:

• Resolves label/relation-type/property strings to integer IDs
• Tracks variable scope and allocates VarIds
• Emits the correct operators (e.g. relationship patterns become Expand, node patterns become NodeScan)
• Populates the [ExprArena] while lowering WHERE / RETURN expressions
• Supports three ontology modes (exploratory / advisory / strict)
