refactor: update project branding and structure for gregFramework

- Changed project title and tagline in docusaurus.config.js to reflect the new branding.
- Updated package.json and package-lock.json to rename the project to gregwiki-docs-site.
- Adjusted sidebar and documentation files to align with the new project structure and naming conventions.
- Enhanced documentation content for clarity and consistency across various sections.
- Added Prettier as a development dependency for code formatting.

This commit aligns the project with the new branding and improves overall documentation quality.

+# Documentation layout (`docs/`)
+
+This folder is the **single source of truth** for the public Docusaurus site. The app lives in the **gregWiki** repository root next to `docs/`; pages are served under the **`/wiki`** base path.
+
+## How content is organized
+
+| Area | Path | Purpose |
+|------|------|--------|
+| **Landing** | [`intro` → `/wiki/docs`](/wiki/docs) | Site home. |
+| **Getting started** | [`getting-started.md`](../getting-started.md) | Onboarding (`getting-started`) + this layout page. |
+| **Workspace** | [`workspace/`](../workspace/) | Map of `gregFramework/` repos on disk. |
+| **Framework** | [`framework/`](../framework/) | Architecture, hooks, Hexmod. |
+| **Plugins** | [`plugins/`](../plugins/) | `FFM.Plugin.*` wiki pages. |
+| **Mods** | [`mods/`](../mods/) | Gameplay mods (`FMF.*`) + framework overview. |
+| **Tools** | [`tools/`](../tools/) | Workshop uploader and related. |
+| **Guides** | [`guides/`](../guides/) | Role-based paths (players, mod developers, contributors, sponsors). |
+| **Releases** | [`releases/`](../releases/) | Per-artifact release notes. |
+| **Reference** | [`reference/`](../reference/) | Naming, catalogs, MCP, release channels. |
+| **Contributors** | [`contributors/`](../contributors/) | Repo inventory, Docusaurus workflow, design system. |
+| **Roadmap** | [`roadmap/`](../roadmap/) | Planning docs. |
+| **Topics hub** | [`topics/`](../topics/) | Cross-cutting overviews (assets, multiplayer, security, …). |
+| **Meta** | [`meta/`](../meta/) | Workshop tooling notes, devserver API, backlog. |
+| **Legacy** | [`legacy/`](../legacy/) | GitHub Wiki mirror under `legacy/wiki-import/`. |
+
+## Legacy GitHub Wiki (`docs/legacy/wiki-import/`)
+
+Long-form pages mirrored from the **GitHub Wiki** live here (synced from `.wiki/`).
+
+1. Clone the wiki working tree as **`../.wiki/`** under `gregFramework/` (same level as sibling repos).
+2. From **gregWiki** root: `npm run wiki:refresh` (or `wiki:sync` → `wiki:normalize-i18n`).
+3. German paired pages live under `i18n/de/docusaurus-plugin-content-docs/current/legacy/wiki-import/` after normalization.
+4. Prefer **new curated docs** under `guides/`, `reference/`, or `framework/`; keep bulk legacy material in `legacy/wiki-import/` until migrated.
+
+Details: [`topics/wiki-import/overview`](../topics/wiki-import/overview.md).
+
+## URLs
+
+- Doc id `intro` → `/wiki/docs`.
+- Typical doc → `/wiki/<doc-id-path>` (e.g. `mods/framework` → `/wiki/mods/framework`).
+
+## Scripts (gregWiki root)
+
+| Script | Role |
+|--------|------|
+| `wiki:sync` | Copies `.wiki/` → `docs/legacy/wiki-import/`. |
+| `wiki:normalize-i18n` | Splits DE/EN pairs into default locale + `i18n/de/...`. |
+| `write-wiki-import-category-keys` | Refreshes `_category_.json` keys under imported trees. |
+
+## Locales
+
+- **Default:** `en` — files under `docs/`.
+- **Deutsch:** overrides under `i18n/de/docusaurus-plugin-content-docs/current/` mirroring `docs/` paths.
+- **fr, es, ru, ja:** fallback to English where no file exists.
