- Introduced a new `unit-test-robot-e2e` target in the Makefile to run end-to-end tests for the robot API, requiring real LLM calls and specific environment setup.
- Updated the `pr-test.yml` and `unit-test.yml` workflows to include a dedicated job for Robot E2E Tests, ensuring proper execution in CI with necessary services and dependencies.
- Enhanced the TODO.md to reflect the completion of various E2E test flows, marking them as done and outlining future integration with OpenAPI.
- Refactored context handling in several test files to utilize `context.Background()` for improved clarity and consistency in execution context.
