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

+title: Legacy wiki import
+sidebar_label: Legacy wiki import
+description: How GitHub Wiki content is mirrored into docs/wiki-import, sorted in the sidebar, and kept in sync with the repo.
+---
+
+# Legacy wiki import
+
+All material under **`docs/wiki-import/`** is part of the **GitHub Wiki mirror**: it is meant to track the wiki that lives alongside the repository, while the rest of **`docs/`** holds **curated** pages (topics, mods, reference).
+
+For a **map of the whole `docs/` tree**, see **[Documentation layout (`docs/`)](../../README.md)**.
+
+## Why this exists
+
+- **Search & versioning**: Wiki text is in Git, reviewable in PRs, and indexed by the site.
+- **i18n**: Paired `Page.md` (DE) + `Page-en.md` (EN) are split by `wiki:normalize-i18n` into the default locale and `wiki/i18n/de/...`.
+- **Sorting**: Audience trees (`EndUser/`, `ModDevs/`, `Contributors/`, `TechnicalReference/`, `DataCenterFAQ/`) use `_category_.json` **positions** so the sidebar order matches intent, not only A–Z. Root **`Home`** uses `sidebar_position: 1` so it appears first among loose pages.
+
+## Keep the mirror up to date
+
+1. Clone or pull the wiki repo into **`.wiki/`** at the **repository root** (same level as `docs/`):
+
+   ```bash
+   git clone https://github.com/<org>/<repo>.wiki.git .wiki
+   ```
+
+2. From **`wiki/`** (the Docusaurus app):
+
+   ```bash
+   npm run wiki:refresh
+   ```
+
+   This runs **`wiki:sync`** (copy `.wiki` → `docs/wiki-import/`) and then **`wiki:normalize-i18n`**. If `.wiki` is missing, `wiki:sync` exits with an error; run `wiki:normalize-i18n` alone only when you are fixing splits without pulling the wiki.
+
+3. Commit changes under **`docs/wiki-import/`** and **`wiki/i18n/de/...`** as needed, then open a PR.
+
+## Editorial policy (recommended)
+
+| Goal | Action |
+|------|--------|
+| **Short-term fix** on the live site | Edit files under `docs/wiki-import/` (and DE mirror if applicable). Optionally backport to `.wiki` so the next sync does not overwrite you. |
+| **Canonical, long-term doc** | Add or move content into **`docs/topics/`**, **`docs/reference/`**, or **`docs/mods/`**, and link from the legacy page. |
+| **Duplicate path** | The folder **`Contirbutors/`** is a typo duplicate of **`Contributors/`**; prefer **`Contributors/`** for new links. |
