Add integration tests for Proof Chain and Reachability workflows
- Implement ProofChainTestFixture for PostgreSQL-backed integration tests. - Create StellaOps.Integration.ProofChain project with necessary dependencies. - Add ReachabilityIntegrationTests to validate call graph extraction and reachability analysis. - Introduce ReachabilityTestFixture for managing corpus and fixture paths. - Establish StellaOps.Integration.Reachability project with required references. - Develop UnknownsWorkflowTests to cover the unknowns lifecycle: detection, ranking, escalation, and resolution. - Create StellaOps.Integration.Unknowns project with dependencies for unknowns workflow.
