"""Unit tests for skill-specific safety policies.

Tests ALL pre-built policies, rules, and actions:
  - 3 keyword rules + 3 LLM fallback rules
  - Block / RaiseException actions (LLM messaging actions covered via policies + mocks)
  - 15 pre-built policies (Block, Block_LLM, Block_LLM_Finder,
    RaiseException, RaiseException_LLM × 3 categories)
  - Full execute() path for both Block and RaiseException variants
  - Integration with Skills container
