feat: add draw.io Cloudron package (Documentation-Tools)

draw.io (diagrams.net) is a client-side diagramming app. It has no user
model and no server-side state (diagrams live in the browser or cloud
storage), so this is the first package to use the Cloudron
authentication-proxy pattern: httpAuth.type=proxy gates access at the
platform edge — the admin restricts who can reach it and the browser
challenges for Cloudron credentials.

- Wraps the official jgraph/drawio:24.7.17 Tomcat image (pinned, verified)
- No database / no persistent storage; installs curl for the health check
- HTTP port 8080, health check on /
- Validated: docker build + run return HTTP 200, container healthy

Gardening: STATUS/README/JOURNAL updated (8/~57 packaged); new
"official-image wrapper + auth proxy" pattern documented in JOURNAL.

+### 8. draw.io (Documentation-Tools) ✅
+**Date**: 2026-07-30
+**Application**: draw.io (diagrams.net) — client-side diagramming tool
+**Package Size**: ~600MB (Tomcat base)
+**Port**: 8080
+**Addons**: none (stateless; no database, no persistent storage)
+
+**Key Learnings**:
+- First package to use the **Cloudron authentication proxy** pattern
+  (`httpAuth.type = proxy`) for a user-less utility app
+- Stateless: diagrams live in browser localStorage or cloud storage (Google
+  Drive, OneDrive, GitHub) — no server-side state at all
+- Verified image tag before pinning via `docker manifest inspect` to avoid a
+  build failure on a non-existent tag
+- Confirmed base image (Tomcat/Debian-slim) lacks curl → installed it in the
+  wrapper for the Docker HEALTHCHECK
+
+**Build Process**:
+- Base: `jgraph/drawio:24.7.17` (pinned, verified tag)
+- `apt-get install curl` for the health check
+- Inherits upstream ENTRYPOINT (`/docker-entrypoint.sh`) + CMD (`catalina.sh run`)
+- No build stage, no runtime setup script needed
+
+**Auth Pattern (NEW)**:
+- draw.io has no user model → use Cloudron `httpAuth.type = proxy`
+- Cloudron admin restricts which platform users reach the app; the browser
+  challenges for Cloudron credentials before the editor loads
+- This is the template for all future stateless / no-user apps
+
+**Validation**:
+- `docker build` → success
+- `docker run` + `curl http://localhost:8080/` → HTTP 200, container healthy
+
+**Files Created**:
+- Dockerfile (official-image wrapper + curl)
+- CloudronManifest.json (port 8080, httpAuth proxy, healthCheckPath /)
+- README.md (auth-proxy usage, features, optional env vars)
+- CHANGELOG.md
+- .env.example (optional DRAWIO_* knobs)
+- logo.png (draw.io brand icon from upstream repo)

+# draw.io Cloudron Package
+
+## Description
+
+draw.io (diagrams.net) is a free, open-source, client-side diagramming
+application for creating flowcharts, process diagrams, organizational charts,
+UML, entity-relationship, network diagrams, and more. It runs entirely in the
+browser; diagrams are stored in browser `localStorage` or exported / synced to
+cloud storage providers (Google Drive, OneDrive, GitHub, GitLab, Dropbox).
+
+This package wraps the official `jgraph/drawio` Docker image (Tomcat serving
+`draw.war`).
+
+## Authentication
+
+draw.io has **no built-in user model** — it is a stateless client-side tool.
+This package therefore uses **Cloudron's authentication proxy**
+(`httpAuth.type = proxy` in `CloudronManifest.json`). The Cloudron admin
+restricts which platform users/groups may reach the app; authorized users are
+challenged for their Cloudron credentials before the diagram editor loads.
+
+This is the recommended pattern for utility apps without their own user
+directory.
+
+## Features
+
+- **Diagram Types**: Flowcharts, BPMN, UML, ERD, network, AWS/Azure/GCP
+  architecture, mind maps, org charts, floor plans, Venn, and more
+- **Shape Libraries**: Hundreds of built-in stencils + custom shape import
+- **Export**: PNG, JPEG, SVG, PDF, HTML, VSDX
+- **Cloud Sync**: Google Drive, OneDrive, GitHub, GitLab, Dropbox, Trello
+- **Offline**: Works fully offline; diagrams persist in the browser
+- **Collaboration**: Real-time co-editing via Google Drive / Microsoft Teams
+- **Embed**: Embed diagrams in Confluence, Jira, Notion, web pages
+
+## Configuration
+
+### Ports
+- **8080**: Tomcat HTTP (the only exposed port)
+
+### Environment Variables (optional)
+draw.io runs out-of-the-box with no configuration. These are optional knobs:
+
+| Variable | Purpose |
+|----------|---------|
+| `DRAWIO_BASE_URL` | Base URL for the deployment |
+| `DRAWIO_SELF_CONTAINED` | `1` to run fully self-contained (no external CDNs) |
+| `PLANTUML_URL` | URL of a PlantUML server for UML rendering |
+| `EXPORT_URL` | URL of a draw.io export server (for server-side PDF/PNG) |
+| `DRAWIO_CSP_URL` | Content Security Policy allowlist |
+
+### Storage
+- **None required.** draw.io is stateless. Diagrams live in the browser or in
+  cloud storage. No Cloudron addons are used.
+
+## Usage
+
+1. Install the package on Cloudron.
+2. In the Cloudron access control, grant the desired users/groups access.
+3. Open the app location — you'll be prompted for Cloudron credentials.
+4. Start drawing. Save diagrams to browser, export to file, or connect a cloud
+   storage provider for persistence.
