Reliable Transcription & Smarter Data Transfer Update

🛠 Fixes

• Fixed infinite loop after transcribing offline chunks when the internet reconnects — the segmentation process now recovers correctly.
• Fixed continuation of mind map creation after a broken AI request once the internet connection is restored — ensures reliable progress.
• Fixed AI parsing to handle unexpected or extra characters in AI responses — improves stability and accuracy.

🔄 Improvements

• Reduced data transfer by keeping embeddings on the server (~100× less data sent to the client) — faster performance and lower mobile traffic.
