feat(editor): add advanced rich text features and update deployment configuration

- Enhance lexical editor with formatting options (strikethrough, inline code, subscript, superscript), lists (unordered, ordered, checklist), tables, alignment, indentation, blockquotes, horizontal rules, uploads, and relationships
- Update Dockerfile for improved build process, including .npmrc support, pnpm config, telemetry disable, and production optimizations
- Modify CI workflow to deploy only, removing local build steps and updating webhook trigger
- Add .dockerignore file and deployment documentation for Docker build and push workflow
- Configure Next.js for standalone output in next.config.js

BREAKING CHANGE: CI workflow now requires local Docker builds before pushing code, as automated builds have been removed.

+---
+
+# Docker Build and Push Workflow
+
+This workflow builds a Docker image locally and pushes it to Docker Hub so it can be deployed to Coolify.
+
+## Prerequisites
+
+1. **Docker Hub Account**: Make sure you have a Docker Hub account
+2. **Docker Hub Login**: Log in to Docker Hub from your terminal
+
+```bash
+docker login
+```
+
+Enter your Docker Hub username and password when prompted.
+
+## Workflow Steps
+
+### 1. Build the Docker Image
+
+Build your Docker image with a tag that includes your Docker Hub username:
+
+```bash
+docker build -t YOUR_DOCKERHUB_USERNAME/website-ricenoodletw-cms:latest .
+```
+
+Replace `YOUR_DOCKERHUB_USERNAME` with your actual Docker Hub username.
+
+You can also add a specific version tag:
+
+```bash
+docker build -t YOUR_DOCKERHUB_USERNAME/website-ricenoodletw-cms:v1.0.0 .
+```
+
+### 2. (Optional) Test the Image Locally
+
+Before pushing, you can test the image locally:
+
+```bash
+docker run -p 3000:3000 YOUR_DOCKERHUB_USERNAME/website-ricenoodletw-cms:latest
+```
+
+### 3. Push to Docker Hub
+
+Push the image to Docker Hub:
+
+```bash
+docker push YOUR_DOCKERHUB_USERNAME/website-ricenoodletw-cms:latest
+```
+
+If you tagged a specific version, push that too:
+
+```bash
+docker push YOUR_DOCKERHUB_USERNAME/website-ricenoodletw-cms:v1.0.0
+```
+
+### 4. Deploy to Coolify
+
+In your Coolify dashboard:
+
+1. Create a new service or edit your existing service
+2. Select **Docker Image** as the source
+3. Enter your image name: `YOUR_DOCKERHUB_USERNAME/website-ricenoodletw-cms:latest`
+4. Configure environment variables if needed
+5. Deploy
+
+Coolify will pull the image from Docker Hub and deploy it.
+
+## Automated Deployment with Gitea Actions
+
+Since building happens locally, the Gitea workflow only triggers Coolify deployment. Here's a sample workflow for `.gitea/workflows/deploy.yaml`:
+
+```yaml
+name: Deploy to Coolify
+
+on:
+  push:
+    branches:
+      - main
+
+jobs:
+  deploy:
+    runs-on: ubuntu-latest
+    steps:
+      - name: Trigger Coolify Deployment
+        run: |
+          curl -X POST "${{ secrets.COOLIFY_WEBHOOK_URL }}"
+```
+
+### Setup Instructions:
+
+1. **Get Coolify Webhook URL**:
+   - In Coolify, go to your service settings
+   - Find the "Webhooks" section
+   - Copy the webhook URL
+
+2. **Add to Gitea Secrets**:
+   - Go to your repository in Gitea
+   - Navigate to Settings → Secrets
+   - Add `COOLIFY_WEBHOOK_URL` with the webhook URL from Coolify
+
+### Workflow:
+
+1. **Build and push locally** (steps 1-3 above)
+2. **Push code to Gitea** - This triggers the Gitea workflow
+3. **Gitea notifies Coolify** - Coolify pulls the latest image from Docker Hub
+4. **Coolify redeploys** - Your service is updated with the new image
+
+**Note**: Make sure your Coolify service is configured to use the Docker image from Docker Hub (`YOUR_DOCKERHUB_USERNAME/website-ricenoodletw-cms:latest`).
