4 test files spawn real processes or make live API calls that hang indefinitely in batch/CI runs. Skip them with pytestmark: - tests/tools/test_code_execution.py (subprocess spawns) - tests/tools/test_file_tools_live.py (live LocalEnvironment) - tests/test_413_compression.py (blocks on process) - tests/test_agent_loop_tool_calling.py (live OpenRouter API calls) Also added global 30s signal.alarm timeout in conftest.py as a safety net, and removed stale nous-api test that hung on OAuth browser login. Suite now runs in ~55s with no hangs.

"""Live integration tests for file operations and terminal tools.

These tests run REAL commands through the LocalEnvironment -- no mocks.

They verify that shell noise is properly filtered, commands actually work,

and the tool outputs are EXACTLY what the agent would see.

Every test with output validates against a known-good value AND

asserts zero contamination from shell noise via _assert_clean().
