perf(entropy): Fix nested imports in hot paths

Hoisted imports from inside frequently-called functions to module level:

app_controller.py:
- Added traceback and inspect at module level
- Removed 3 nested traceback imports from exception handlers

gui_2.py:
- Added traceback at module level
- Removed nested traceback import from _gui_func exception handler
- Kept uvicorn lazy-loaded (only for --headless mode)

multi_agent_conductor.py:
- Removed unused 'import sys' from run()
- Removed redundant nested imports (already at module level)

Also adds audit scripts and entropy findings documentation.
