- Add prompt_intents tracking to IntentProbe.build_prompts() so each prompt maps back to its source intent (fixes test_cas_intentprobe)
- Fix test_spo_augmentation fixtures to load intent service before constructing SPO probes, use TextStub objects instead of raw strings, and align assertions with actual implementation (augment_system/ augment_user flags instead of nonexistent augmentation_func attribute). Add _mint_attempt tests that exercise the base Probe method with augmentation metadata verification.
- Load intent service in langservice probe_pre_req fixture and skip TAPIntent/PAIR in translation test only when OPENAI_API_KEY is missing
- Sync requirements.txt datasets version (3.x -> 4.x) with pyproject.toml
