fix: Improve text filtering and add validation to skill parsing

PROBLEM: UI text like 'Position Skills window Wounding' and
'Scan Current Page Serendipity' was being parsed as skills.

FIXES:

1. Enhanced is_valid_skill_text() filtering:
   - Added more UI patterns: 'Position Skills', 'Scan Current Page',
     'Select Area', 'Drag over', 'Navigate pages'
   - Added combined patterns: 'Combat Wounding', 'Scan Serendipity',
     'Position Wounding', etc.
   - Added action word detection: Click, Scan, Position, Select,
     Navigate, Start, Save, Clear - any line with these is UI text
   - Reduced max words from 10 to 7 for skill names

2. Added validation in _parse_skills_from_text():
   - After extracting skill name, validates with is_valid_skill_text()
   - Logs filtered names for debugging
   - Only adds to results if validation passes

USER ACTION NEEDED:
- Pull latest code: git pull origin main
- Select Area button should appear in UI
- Drag to select your Skills window area
- Scan will only read from that area

This should eliminate UI text from scan results.
