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

+description: "Aktueller Stand nach Repo-Split: Wrapper-Struktur, Core-Build und Mod-/Extension-Repos."
+---
+
+Die Struktur ist jetzt **Multi-Repo** mit `gregFramework/` als lokalem Wrapper-Ordner. Darin liegen die eigenständigen Repositories, z. B.:
+
+- `gregCore/` (Core SDK, inkl. `FrikaMF-StandaloneRepo/`)
+- `gregMods/` (einzelne Mod-Repos)
+- `gregExtensions/` (einzelne Extension-Repos)
+- `gregWiki/` (Dokumentation)
+
+`DataCenter-RustBridge` wird in den Core integriert und liegt im Core-Baum unter:
+
+- `gregCore/FrikaMF-StandaloneRepo/bridges/gregSta.RustBridge/`
+
+## Core bauen
+
+```text
+dotnet build gregCore/FrikaMF-StandaloneRepo/FrikaMF.sln -c Release
+```
+
+Alternativ in IDE: `gregCore/FrikaMF-StandaloneRepo/FrikaMF.sln` öffnen.
+
+## Hook naming
+
+- **Target convention:** `FMF.<DOMAIN>.<Event>` (see [`CONTRIBUTING.md`](https://github.com/mleem97/gregFramework/blob/master/CONTRIBUTING.md)).
+- **Registry:** [`FrikaModFramework/fmf_hooks.json`](https://github.com/mleem97/gregFramework/blob/master/FrikaModFramework/fmf_hooks.json).
+- **Legacy runtime strings** may still use `FFM.*` in [`HookNames`](https://github.com/mleem97/gregFramework/blob/master/framework/FrikaMF/HookNames.cs) until migrated.
+
+## Mod starten
+
+1. Neues Mod-Repo unter `gregMods/` nach Schema `gregMod.<Name>` anlegen.
+2. Templates aus `gregCore/FrikaMF-StandaloneRepo/Templates/` nutzen.
+3. Hook-Metadaten pflegen und Mod im eigenen Repo versionieren.
+
+## Documentation site
+
+- **Repo:** `gregWiki/`
+- **Inhalt:** Markdown/MDX in diesem Repo, angepasst an den Split-Stand.
+
+### Docker
+
+- **Dev server with hot reload:** from the `gregWiki` repo root, `docker build -t gregwiki-docs .` then `docker run --rm -p 3000:3000 gregwiki-docs` (or use your host compose file if you mount this repo).
+- **MCP:** see [`reference/mcp-server`](./reference/mcp-server.md) in the core repository (`gregCore/FrikaMF-StandaloneRepo/mcp-server/`).
+
+## Assistants / MCP
+
+Der MCP-Server für Framework-Scan/Tooling liegt im Core-Umfeld (`gregCore/FrikaMF-StandaloneRepo/mcp-server/`).
