test(e2e): add minimal startup E2E tests
Add E2E tests for LangBot startup flow: - tests/e2e/utils/config_factory.py: minimal config generation - tests/e2e/utils/process_manager.py: LangBot subprocess management - tests/e2e/conftest.py: E2E fixtures (session-scoped process) - tests/e2e/test_startup.py: 12 tests for startup verification Tests verify: - boot.py + stages execution - database initialization (SQLite) - API availability - migrations applied Uses embedded databases (SQLite, Chroma) - no external dependencies.
