## Description

Meta task that clusters all graph module tasks. Once complete, the core FlowGraph class supports operation graph construction, call graph construction from events, JSON serialization, all query methods, and graph validation.

## Acceptance Criteria

- [ ] All graph tasks completed
- [ ] FlowGraph class works for both `OperationGraph` and `CallGraph` type parameterizations
- [ ] JSON round-trip is lossless
- [ ] DAG invariants enforced at construction time
