Batch 4: Standardize structure and metadata

- Rename System Architec/ → System Architecture/ (fix truncated name)
- Add standard frontmatter to all 6 hub files (Blog, Finance, Health, House, Personal Development, Productivity)
- Add frontmatter to key content files (Brand and models, Task triage)
- Standardize tags format (lowercase, hyphen-separated)
