- Rework Settings tab into grouped sections
- Add preferred-region matching and full-hash-by-default setting
- Replace combo-box square arrow with a proper chevron
- Fix UMD Refresh button (clicked bool was clearing the view)
- Remove pkg2zip.exe fallback (pure-Python decryptor is the primary path)
- Move LAN IP/share paths to .env; use example defaults in config
The fuzzy fallback ran difflib against every catalog release (~11k) for each
unmatched disc, dominating library load (2.7s) and startup scans. Pre-filter
candidates to those sharing a significant (>=3 char) word with the disc
filename or PARAM.SFO title before the expensive comparison, and cache the
pre-computed word sets. Library load: 2.7s -> 0.44s; scan: ~0.5s.
