Fix suitbuilder early termination and add armor level scoring

Bug fixes:
- Remove "TEMPORARY FIX" that stopped search after finding first suit
- Add armor level as lowest-priority tiebreaker in scoring

Scoring formula now:
- Set completion: +1000 per complete set
- Missing pieces: -200 penalty each
- Crit damage: +10/20 per item
- Damage rating (clothes): +10/20/30
- Spell coverage: +100 per fulfilled spell
- Base item score: +5 per item
- Armor level: +1 per 100 AL (tiebreaker)

Updated design doc with audit findings - most features were already
working correctly. The magsuitalgo.md analysis was outdated.
