v0.1.2

AI diagnosis fixes

• Default model is now nvidia/nemotron-3-ultra-550b-a55b:free (deepseek/deepseek-v4-flash:free was retired from OpenRouter's free tier and broke Generate AI analysis with a 502). Override with OPENROUTER_MODEL.
• /api/ai-diagnosis no longer leaks model failures as HTTP 500: missing httpx → 503, other model errors → 502 with the cause attached. The frontend now shows the backend's error detail.

Timeline polish

• Graph and Timeline share one view budget; gaps scale with zoom; slimmer lanes; fitScale fills short traces.

Automation

• New Trusted Publishing workflow: creating a v* release runs tests, builds, and publishes to PyPI automatically.
