fix: include thought signatures for gemini-3-pro native tool calls

Browse source 
Gemini 3.0-pro requires thought_signature field in functionCall parts
even when reasoning is not enabled. This fix ensures that thought
signatures are always included for gemini-3-pro models when using
native tool calls to prevent "Function call is missing a thought_signature"
errors.

Fixes #9499
