refactor(seeder): reframe problematic profiles for realistic data generation

- Rename "⚖️ Balanced Mix" → "⚖️ Multi-Weak Remediation" to match actual output
- Update intention notes to reflect BKT's natural tendency to push skills to extremes
- Remove tuning criteria that fought against realistic behavior
- Focus profiles on app feature coverage rather than perfect BKT states
