fix: agent-native audit — parameterize thresholds, add CRUD tests, tool discovery

Audit fixes for agent-native architecture gaps:

- agent_tools/content.py: parameterize healthy_threshold in check_embedding_quality
- agent_tools/__init__.py: add __all__ exports and list_tools() runtime discovery
- agent_tools/database.py: add CRUD primitives (create_motion, update_motion, delete_report)
  plus query_embeddings, query_similar_motions, query_compass_positions
- tests/agent_tools/test_database_tools.py: add CRUD tool tests
- tests/agent_tools/test_content_tools.py: add parameterized threshold test
- tests/agent_tools/test_package.py: test list_tools() and package imports

Tests: 245 passed, 3 skipped
