Feature/smoke tests

[JohannesRudolph]

This moves smoke test code from our internal test suite into the public hub.

I'm not 100% happy with consistency in all cases (e.g. use of test_context for common test vars vs. specific variables only needed by some tests) but this is something we can follow up on later.

Azure Virtual Machine Starterkit

Platform: azure

Path: /home/runner/work/meshstack-hub/meshstack-hub/modules/azure/azure-virtual-machine-starterkit/buildingblock/logo.png

AI Prompt (copy this to image generator)

Create a professional flat design icon for the meshcloud Building Block ecosystem.

Purpose: The Azure Virtual Machine Starterkit provides application teams with a pre-configured Azure environment. It includes a dedicated project, an Azure tenant, and a virtual machine for quick provisioning and testing.

Visual Style:
- Plain white background (#FFFFFF) for easy removal in post-processing
- Background will be converted to transparent (see post-processing steps)
- Use Azure colors: blue (#0078D4), cyan (#00BCF2), and light blue (#50E6FF) as accent colors
- Maximum 2-3 colors total
- Simple geometric shapes with clean lines
- Flat design (no gradients, shadows, or 3D effects)
- Minimalist, modern appearance

Composition:
- Square centered layout (NOT horizontal)
- Icon fills the entire canvas edge-to-edge (100% of area)
- No padding or margins around the icon
- Symmetrical arrangement
- Platform-appropriate symbol for AZURE (e.g., cloud, container, database, server, etc.)

Style: Enterprise professional, instantly recognizable at small sizes, similar to app icons or logos.
Dimensions: 800x800 pixels

Post-Processing Instructions

Step 1: Remove white background with GIMP (free)

a) Open image in GIMP
b) Right-click layer → "Add Alpha Channel"
c) Tools → "Select by Color" (Shift+O)
d) Click white background
e) Press Delete key
f) File → Export As → logo.png
g) Set Compression level to 9 → Export

Step 2: Resize to 800x800 pixels if needed

• GIMP: Image → Scale Image → 800x800px
• Or use any image editor

Step 3: Compress with pngquant (free command line tool)

• Install: brew install pngquant (Mac) or apt install pngquant (Linux)
• Run: pngquant --quality=20-30 logo.png --ext .png --force
• This reduces file size by 60-80% while maintaining quality

Target specs: 800x800px PNG with transparent background, under 100KB
