refactor: Remove debug scripts and temporary test files

Cleaned up repository root by removing:
- QA verification scripts (moved to external docs)
- Debug timeline tests
- Temporary test databases and logs
- Issue verification reports and JSON files

Keeps only essential project files:
- Configuration files (.prettierrc.json, eslint.config.js, etc.)
- Package management (package.json, package-lock.json)
- Build tools (tsconfig.json, jest.config.js)
- Core documentation (README.md, API.md, etc.)

Repository now has clean, professional structure focused on production code.
