Restructure and reorganize documentation

Moved and renamed documentation files to new topic-based directories (ai, data-access, logic, modeling, server, reference, getting-started). Added meta.json files for navigation. Removed outdated or redundant docs including contributing, development plan, and example/tutorial files. Updated frontmatter in AI and data-access docs for improved descriptions.
