Pull request overview

This PR adds first-class support for Google ML Kit GenAI APIs (Summarization, Proofreading, Rewriting, Image Description, Speech Recognition, and Prompt) to the Flutter plugin suite, wires them into the umbrella google_ml_kit package, updates the example app, and standardizes licensing metadata.

Changes:

• Introduces new GenAI Flutter plugins (Android + iOS shims) for summarization, proofreading, rewriting, image description, speech recognition, and generic prompt-based generation, plus corresponding documentation and wiring in scripts.
• Updates the umbrella google_ml_kit package, root README, and example app to advertise and reference the new GenAI features.
• Standardizes LICENSE headers across the repository to attribute copyright to flutter-ml.dev (2026).
