Organize documentation: move analysis files to dedicated folder

Moved temporary analysis files to .claude/docs/analysis/ for better organization:
- CLAUDE_MD_UPDATES.md - Implementation guide
- claude-md-improvements.md - Root cause analysis
- Added README.md explaining the purpose of these files

This keeps the root directory clean while preserving valuable historical
context and analysis for future reference.
