Pull request overview

Note

Copilot was unable to run its full agentic suite in this review.

Removes several unused MessagePiece fields and associated memory/query surface area, and updates tests/docs to match the simplified model.

Changes:

• Removed originator, scorer_identifier, and targeted_harm_categories from MessagePiece serialization and memory storage.
• Changed scores hydration to occur post-construction via MessagePiece._set_scores() (memory layer + tests updated).
• Removed targeted_harm_categories filtering capability from MemoryInterface.get_attack_results() and DB-specific implementations.
