Merge Docusaurus site: all content under docs/, align with gregFramework split layout

- Move markdown and wiki-import tree into docs/; keep app shell at repo root
- Point docusaurus docs path to docs/; edit links to mleem97/gregWiki
- Sync and i18n scripts use gregWiki root and ../.wiki under gregFramework
- Sidebars: workspace layout from root docs ids; plugins under mods/extensions
- Fix redirects, module catalog URLs, release note paths, and wiki-import category keys
- Update repo inventory for split repos; Dockerfile for single-repo context
