Add comprehensive Vision API support and examples

Introduces full Vision API feature parity with Node.js/JSR SDK, including advanced methods for image analysis, OCR, object detection, accessibility descriptions, batch processing, image comparison, and caption generation. Adds new example files demonstrating all vision capabilities, updates README and CHANGELOG with detailed documentation and usage patterns, and enhances error handling, retry logic, type hints, and endpoint management. Bumps version to 1.7.5 and updates distribution files accordingly.
