Standardize heading hierarchy in agents.md documentation

• Changed individual agent sections from #### to ### for consistency
• Fixed 13 agent section headers: system-architect, backend-architect, frontend-architect, devops-architect, security-engineer, performance-engineer, root-cause-analyst, quality-engineer, refactoring-expert, python-expert, requirements-analyst, technical-writer, learning-guide
• Ensures consistent hierarchy: # (title) → ## (main sections) → ### (subsections)
• Improves document navigation and accessibility
