Tests that launch the API server via subprocess used a hardcoded
"python" command which fails on systems where only "python3" is
available (e.g. macOS). Using sys.executable ensures the same
interpreter running pytest is used for subprocesses.
Fixes 36 test errors on macOS environments.
- Made reward field truly optional in messages (no auto-addition)
- Accept custom roles (dog, cat, etc.) beyond standard ones
- Added 24 new tests for edge cases (tuples, unicode, large content)
- Reorganized test structure: moved from testing/ to atroposlib/tests/
- Fixed legacy API tests and removed tests requiring missing data files
All 43 tests pass\! Fixes message handling for SFT use cases.
