MessageAnalyzer class

Analyzes user messages to infer metadata before they are sent to the AI.

Used by Prompt to resolve ResponseLanguage.auto and ResponseTone smart defaults — it reads the message and picks the right values so developers don't have to.

All methods are static, pure, and free — no API calls, no side effects.

MessageAnalyzer.detectLanguage('مرحبا كيف حالك');   // arabic
MessageAnalyzer.detectLanguage('Hello, how are you?'); // english
MessageAnalyzer.detectLanguage('Hi مرحبا');           // bilingual

MessageAnalyzer.isQuestion('what is Flutter?'); // true
MessageAnalyzer.isQuestion('ما هو فلاتر؟');    // true

MessageAnalyzer.detectTone('hi');               // casual
MessageAnalyzer.detectTone('Can you explain...'); // friendly
MessageAnalyzer.detectTone('Analyze this full document and provide...'); // formal
