diodiogod 6c87d67ed7 Add YAML-driven engine documentation table generator

- Created comprehensive YAML source of truth for all TTS engines
- Implemented Python generator for 3 documentation tables:
  * ENGINE_COMPARISON.md - Main engine overview with capabilities
  * LANGUAGE_SUPPORT.md - Detailed language support matrix
  * FEATURE_COMPARISON.md - Feature capabilities comparison
- YAML captures all engine metadata without information loss
- Tables auto-generated via scripts/generate_engine_tables.py
- Added flag emojis to language support table for easy scanning
- Speed performance fixes: F5-TTS marked as "Very Fast"
