Mined the egirl->cocotte lineage + the prose agentic configs. Per-language
standards (py/rust/gd) and general conventions: service_architecture,
multi_agent_workflow, error_handling_logging, mcp_server_patterns,
naming_conventions, tenancy_patterns (draft), database_patterns. Captures the
canonical/latest where versions diverged. 14/14 lint:yaml-valid.
