Agent Evidence SE Workflow Case Prototype v0.1.0-rc3

Representative reproducible software engineering workflow fixtures for operation-accountability profile validation. This rc3 release candidate repairs rc2 asset reproducibility by providing an installable source package, top-level evidence documents, selected pytest truth, reports, and reproducibility materials. It does not claim industrial real-world evaluation, production deployment, benchmark superiority, legal or compliance sufficiency, full FDO interoperability, or TSE v3 readiness.
