Remove unnecessary pass statement in Gemini retry exception handler

[Copilot]

Addresses code review feedback from PR #2 to remove redundant pass statement in inference_commercial_api.py.

Changes

• Removed unnecessary pass statement at line 722 in exception handler
• Retained explanatory comment that clarifies control flow

The pass statement added no functional value since the comment already documents the fall-through behavior:

except Exception as text_e:
    if verbose_block_logging:
        print(f"   Warning: Had parts but couldn't extract text: {text_e}")
    # Fall through to error handling below
