feat: add evaluate_task.py CLI, tasks/ corpus, and pyproject.toml

Adds the Kealu-specific evaluation interface for kealu-bench integration:
- evaluate_task.py: single-task Docker evaluator CLI (KEA-14079 AC #2-logic-star-ai#5)
- tasks/: pre-exported BaxTask corpus, 392 JSON files (28×14, AC logic-star-ai#6-logic-star-ai#7)
- pyproject.toml: pip-installable package descriptor for editable install (AC logic-star-ai#8)
