MiniMax changed from category_remains[text_generation] with count fields
to model_remains[general] with remaining_percent fields. Now tries v2

Probes Anthropic OAuth and MiniMax subscription usage and displays
percentage consumed for 5-hour and 7-day windows with colour-coded output.
Ported probe logic from agent-runtimes/scripts/ralph_code.
