Refresh Lemonade Playbook

[vgodsoe]

Addresses:

• Fixes stale commands due to breaking changes in the Lemonade 10.2.0 release
• Uses the newer Gemma 4 model
• Addresses branding requirements
• Removes the getting started section. Closes [Bug]: Point the Lemonade installation 'Getting started' section to <!-- @require:lemonade --> #214
• Updates a screen capture with the newer model selection
• Update the tagline for the playbook to be more descriptive and less device specific.
• CI tests updated
  • Removed explicit server start/stop steps (Lemonade server now auto-starts in the background on install)
  • Standardized usage to port 13305
  • Model updated from Gemma-3-4b-it-GGUF→ Qwen3.5-4B-GGUF
  • Lemonade Python Smoke Test updated:
    • Added retry logic in lemonade_python_smoke.py as I faced intermittent transport/startup readiness with Lemonade v10.2.0
      • /api/v1/models being reachable is not always sufficient to guarantee that the first completion request will succeed.
      • API may be up, but request still fails with Lemonade returning a network_error / "CURL error: Couldn't connect to server"
    • Used a larger max_tokens (5000)
    • Validates that we got exactly two flashcards
    • Validates that each card has both keys and that the values are strings
    • Prints the raw response (only if it exists)

Changes look great!
@sreeram-11 Would still be great if you could take a look to make sure tests are passing
