feat: add automated docs pipeline and scaffold /docs folder

- Add sync-docs CI job: runs on push to main, copies /docs into sencho-docs repo via DOCS_REPO_TOKEN
- Scaffold /docs with mint.json, getting-started/introduction.mdx, getting-started/quickstart.mdx, features/overview.mdx
- Update CHANGELOG

+description: A high-level tour of everything Sencho can do.

+
+## Stack management
+
+Deploy, start, stop, restart, and remove Docker Compose stacks through a point-and-click interface. Edit `docker-compose.yml` files directly in the built-in Monaco editor.
+
+## Multi-node support
+
+Add remote Sencho instances as nodes. All dashboard operations — stack management, logs, stats — work identically whether you're targeting your local machine or a server on the other side of the world.
+
+## Real-time logs & stats
+
+Stream container logs and resource metrics (CPU, memory, network I/O) live in the browser via WebSocket connections.
+
+## Resources hub
+
+View and manage all Docker images, volumes, and networks. Resources are classified as:
+
+| Label | Meaning |
+|-------|---------|
+| **Managed** | Owned by a Sencho stack |
+| **External** | Part of another Compose project |
+| **Unused / System** | Reclaimable or Docker-internal |
+
+Run scoped prune operations to clean up Sencho-managed resources only, or target all Docker resources when needed.
+
+## Notifications & alerts
+
+Configure threshold-based alerts for CPU and memory usage. Notifications surface in the dashboard and can be dismissed or cleared in bulk.

+title: Introduction
+description: What Sencho is and why you might want it.
+---
+
+Sencho is a self-hosted Docker Compose management dashboard. It gives you a clean web UI to deploy, manage, and monitor your Docker Compose stacks — locally or across multiple remote servers — without touching a terminal.
+
+## Key concepts
+
+- **Stacks** — a Docker Compose project living in your `COMPOSE_DIR`. Sencho treats each subdirectory as a stack.
+- **Nodes** — a Sencho instance. Your local machine is always the default node. Add remote nodes by pointing Sencho at another Sencho instance's API URL.
+- **Resources** — images, volumes, and networks that belong to your stacks (managed) or exist outside them (external/unused).
+
+<Note>
+  Sencho never accesses remote servers directly via SSH or Docker TCP. Remote management works by proxying API requests to another running Sencho instance.
+</Note>

+title: Quickstart
+description: Get Sencho running in under five minutes.
+---
+
+## Prerequisites
+
+- Docker and Docker Compose installed on the host
+- A directory where your Compose projects live (e.g. `/opt/compose`)
+
+## Run with Docker
+
+```bash
+docker run -d \
+  --name sencho \
+  -p 3000:3000 \
+  -v /var/run/docker.sock:/var/run/docker.sock \
+  -v /opt/compose:/app/compose \
+  -v sencho_data:/app/data \
+  -e JWT_SECRET=change-me \
+  ghcr.io/ansоcode/sencho:latest
+```
+
+Open `http://localhost:3000` in your browser. On first boot you'll be prompted to create an admin account.
+
+<Note>
+  Replace `/opt/compose` with the path to your Compose projects directory. Every subdirectory inside it becomes a stack in Sencho.
+</Note>
+
+## Next steps
+
+- [Add a remote node](/features/overview) to manage another server from the same dashboard
+- Browse your stacks, start/stop services, and tail logs from the dashboard
