Fix agentic module syntax errors and locale-sensitive test assertion

- Fix Python 2-style except syntax in orchestrator.py, agent.py, state.py:
  `except X, Y:` -> `except (X, Y):` with fmt: skip to prevent ruff
  formatter bug from reverting the fix
- Make StatsPage quality score assertion locale-tolerant (82.5 -> /82[.,]5/)
