v2.7.3

What's Changed

Bug Fix

• fix: use max_input_tokens for context window size (#216)
  • TokenCounter.get_max_tokens() was using litellm.get_max_tokens() which returns the output token limit (max_tokens), not the input context window (max_input_tokens)
  • Switched to litellm.get_model_info() and reading max_input_tokens, with fallback to max_tokens if unavailable
  • Uses explicit None check instead of or operator to correctly handle falsy values like 0
  • This fixes utilization being overstated by up to 8x for models where output limits are much smaller than context windows

Closes #215
