Per user direction: use a real provider instead of mocks. The 10 sim
tests that previously set current_provider='gemini_cli' + gcli_path to
tests/mock_gemini_cli.py now set:
current_provider='minimax'
current_model='MiniMax-M2.7'
Removed the gcli_path setters (no longer needed). Updated comments
that mentioned 'Use gemini_cli with the mock script'. Updated
test_sim_ai_settings.py provider mock to minimax.
tests/mock_gemini_cli.py + mock_gcli.bat retained as a backstop (no
longer used by any current test). tests/test_cli_tool_bridge*.py
GEMINI_CLI_HOOK_CONTEXT references retained (meta-tooling, separate).
This fixes the 'stuck' behavior in concurrent tests by ensuring the tests look for standard completion markers and don't wait for unnecessary timeouts.
