v1.2.0

What's Changed

• *Merged \�ision_helper_quick_analyze\ into \�ision_helper_analyze_image* — pass \quick: true\ for a fast, cheap single-image analysis (quick model, 1024-token output cap, minimal reasoning). One fewer tool in the catalog, no duplicated code.
• *Simplified \�ision_helper_list_models* — removed the
  esponse_format: json\ mode; markdown-only output with a leaner description.
• Retry fixes — \Retry-After\ is capped at 15 s, no wasted backoff sleep after the final attempt, and malformed 2xx responses fail immediately instead of being retried.
• Registry refresh — Windows registry values are re-read on a 60-second cycle, so an updated \setx OPENROUTER_API_KEY\ is picked up without restarting the client (matching documented behavior).
• Leaner tool descriptions — cut roughly 40-60% per tool since they duplicated the parameter schema docs.
• Tests + CI — 18 unit tests (registry parsing, MIME sniffing, image loading, error mapping, truncation) and a GitHub Actions workflow across Node 18/20/22.
• Docs — README updated for the merged tool and corrected working-directory/registry wording.
