v2.2.20 - Smarter Query URL Rendering

This release improves the rendering and UX of suggested follow-up question URLs.

Changes:

• Plain-text URL detection: URLs like https://chat.virtualflybrain.org?query=... are automatically converted to clickable links
• Smart link labels: when text precedes the URL (e.g., What is the medulla https://...), the question becomes the link text—no ugly encoded URLs shown to users
• Fallback handling: if only the URL exists, the decoded query text is used as the link label
• Enhanced system prompt guidance with real-world examples, emphasis on URL-encoding, and advice on varying question types

Result: Whether the LLM generates plain-text URLs or markdown links, they're now rendered cleanly with readable question text as the clickable label.
