feat: Add text analysis checks for CV verification

Implement four new CV verification checks without external APIs:

1. Buzzword detection - flags excessive clichés (50+ patterns)
2. Vague achievement detection - identifies weak language vs quantified results
3. Skills/job title alignment - checks skills match claimed roles (25+ role mappings)
4. Unrealistic metrics detection - flags implausible claims (>200% growth, etc.)

New files:
- ITextAnalysisService interface
- TextAnalysisResult models
- TextAnalysisService implementation (~400 lines)

Integration:
- Added "Analysing Content" processing stage
- Flags appear under Plausibility category
- TextAnalysis section added to veracity report
