[d1maash]

Summary

This PR adds a smart file renaming feature that automatically converts unreadable filenames (like IMG_20240315_123456.jpg) into meaningful, human-readable names (like Анталья - Март 2024.jpg) using EXIF metadata and AI analysis.

Changes Made

New Files

• src/ai/smart-renamer.ts - Core service for intelligent filename generation
• src/utils/geocoding.ts - Offline reverse geocoding utility with 150+ cities database

Modified Files

• src/cli.ts - Added new sortora rename command

Features

SmartRenamer Service

• Detects unreadable filename patterns (IMG_, DSC_, PXL_*, WhatsApp files, etc.)
• Extracts date and GPS coordinates from EXIF metadata
• Converts GPS coordinates to city/country names using offline geocoding
• Uses AI classification to determine content type (photo, screenshot, document, etc.)
• Supports OCR for reading text from images
• Batch renaming with automatic grouping by date and location

Offline Reverse Geocoding

• Database of 150+ major cities worldwide (Russia, CIS, Europe, USA, Asia, popular resorts)
• Finds nearest city within 100km radius
• No external API calls required - fully offline
