fix: add missing config to Gemini client invoke method

[shrisukhani]

Summary

• Fixed bug where GeminiClient.invoke() was not passing temperature and maxOutputTokens to the API
• The invokeStructured() method correctly included these parameters, but invoke() did not
• This caused users' temperature settings to be silently ignored for regular (non-structured) Gemini calls

Changes

Added the missing config block to match invokeStructured():

config: {
  temperature: options?.temperature ?? this.temperature,
  maxOutputTokens: options?.maxTokens ?? this.maxTokens,
},

Test plan

• Verify TypeScript compiles without errors
• Test Gemini provider with explicit temperature setting to confirm it's respected

Note

GeminiClient.invoke now forwards temperature and maxTokens (as config.maxOutputTokens) to the Gemini API.

• Gemini provider (src/llm/providers/gemini.ts):
  • Add config to invoke request, forwarding temperature and maxOutputTokens to the API.
