- Move agent code from backend/src/agent/ to agent/src/ss_tools/agent/ - Extract shared stdlib-only utilities to shared/src/ss_tools/shared/ - Add #region/#endregion contracts to all ~140 functions (INV_1 compliance) - Update docker files, entrypoint, build scripts for new package layout - Backend now imports ss_tools.shared._llm_health (no gradio/langchain deps) - Add specs for 036-039 feature plans
