Privacy: Inference log files grow indefinitely with no rotation

[0xharkirat]

Priority: High

InferenceLogger appends every command resolution attempt (transcript, parameters, timestamps) to JSONL files in getApplicationDocumentsDirectory()/inference_logs/. These files:

• Accumulate indefinitely (one file per day, never deleted)
• Contain the full text of everything the user has ever said to the assistant
• Are accessible via device file manager and backup systems

Recommended fix

• Add log rotation (e.g., delete files older than 7 days)
• Consider disabling logging entirely in release builds
• Or make it opt-in via a settings toggle

Files

• lib/services/inference_logger.dart (lines 53-75)
