Add quality_analyzer.py — PDF quality scoring for FOIA/CIA filtering

Scans PDF folders and scores each document (0-100) based on:
- Text content (word count, coherence, OCR garbage detection)
- Font presence (scanned vs text-based)
- File size, page count, filename quality
- Language detection (Arabic/Russian/Turkish/English)

Labels: high (70+), medium (40-69), low (20-39), noise (<20)
Outputs JSON + CSV. Can move noise to Arsiv/noise with --move.

Usage: --scan, --report, --export-csv, --move [--confirm]
