"""
End-to-end tests for critical user workflows.

This test suite validates complete user journeys end-to-end:
1. Agent execution workflow (creation, execution, monitoring, results)
2. Skill loading workflow (import, scan, install, execute)
3. Package installation workflow (request, governance, install, execute)
4. Multi-provider LLM workflow (provider selection, fallback, streaming)
5. Canvas presentation workflow (creation, LLM content, present, feedback)
6. End-to-end smoke tests (complete user journeys)

These tests use real services (PostgreSQL, Redis, LLM providers) to validate
actual system behavior, not mocked components.
