Moved contribution-related docs to docs/contribution/, added new guides and templates for contributors, and updated references in docs/README.md to point to the new locations. This improves organization and provides clearer onboarding and standards for new contributors.
Introduced new and updated documentation files across the docs/ directory, including project structure guides, function library references, and standardized READMEs for ct, install, vm, tools, api, and misc. This update fully documents all nine function libraries, provides quick start and learning paths, and mirrors the project structure for easier navigation and contribution.
