fix: remove unused lru_cache import and update test expectations

- Remove unused functools.lru_cache import from refactor_tool.py
  (fixes ruff TID251 banned import error)
- Update test_all_tools.py to include new packages:
  config (2 tools), mcp_tools (4 tools), llm (0-4), vector (0-3)
- Make agent tool count flexible (10-12) for platform differences
- Total tools now 57-66 depending on optional dependencies
