Detailed Description

Pure JSON-definition → CompiledGraph parser, extracted from GraphEngine.

GraphCompiler turns a JSON graph definition into a CompiledGraph — a value-type bundle of channels, nodes, edges, barriers, interrupts, and retry policy. It has NO knowledge of runtime (threading, checkpointing, execution) and NO dependency on GraphEngine; it depends only on NodeFactory (to instantiate GraphNode subclasses).

Why a separate stage: parsing failures surface here cleanly (malformed edge, unknown reducer, missing node type) before any runtime state is constructed, and the resulting CompiledGraph can be inspected or mutated in tests without spinning up the engine.
