libs/genai/v3.0.1

Adds new functionality for video processing optimization and API endpoint customization, along with important bug fixes for thinking.

• MediaResolution parameter support (#1259) - Added media_resolution configuration to ChatGoogleGenerativeAI for optimizing video understanding. Setting MediaResolution.MEDIA_RESOLUTION_LOW can reduce input token usage by 3x+ for video processing tasks.
• Base URL customization (#1278) - Added base_url parameter as an alias for configuring custom API endpoints. This parameter maps to client_options['api_endpoint'].
• Extended thinking signature handling (#1269) - Fixed thought signature extraction during v1 content translation. The conversion function now properly decodes and preserves base64-encoded thought signatures from text blocks.
