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

+
+# Release channels — Steam vs GitHub
+
+This project uses **two complementary channels** for distributing mods and plugins. The wiki and [`/mods`](/mods) catalog are **not** a replacement for the Steam Workshop; they are an **overview**, documentation hub, and **second official source** for files that should not flood the Workshop.
+
+## Steam Workshop (discovery & stable)
+
+- **Game**: [Data Center on Steam](https://store.steampowered.com/app/4170200/) (AppID `4170200`).
+- **Workshop**: [Browse items](https://steamcommunity.com/workshop/browse/?appid=4170200) — best for **player discovery**, ratings, and stable “subscribe and play” flows.
+- Use Workshop for **production-ready** releases you want every player to see.
+
+## GitHub Releases (beta and alternate downloads)
+
+- **Organization**: [github.com/mleem97/gregFramework](https://github.com/mleem97/gregFramework) (see repo for actual org if renamed).
+- **Stable**: tagged releases — same DLLs you may also ship via Workshop.
+- **Pre-release / beta**: GitHub **pre-releases** — ideal for testers without publishing unfinished items to Workshop.
+- **Why**: avoids “polluting” the Workshop with experimental builds while still offering a **single official URL** for power users and CI.

+## This documentation site
+
+| Need | Where |
+|------|--------|
+| Wiki entry for a module | `/wiki/mods/...` |
+| Download link (when configured) | GitHub Releases asset or redirect from [`moduleCatalog`](https://github.com/mleem97/gregFramework/blob/master/wiki/src/data/moduleCatalog.ts) |
+| Catalog overview | [`/mods`](/mods) |
+
+## Maintainer checklist
+
+- [ ] Stable: tag + Release notes + optional Workshop update.
+- [ ] Beta: pre-release + link from module wiki page + `releaseReady: false` in catalog until promoted.
+- [ ] Do not commit large binaries to `main` without a documented policy.
