openai/gpt-chat-latest → B (4:1)

Side B consolidates canonical path normalization and URL construction into shared `slug_types::paths` newtypes (`GardenItemUrl`, `ForumThreadUrl`, `TildeOntologyPath`) and updates API/RPC types to use them, eliminating duplicated string-building logic across the server. Side A replaces a complex autocomplete parser with a much simpler paste-and-go flow and removes substantial UI, JS, and parser infrastructure; while it likely improves reliability, it is primarily a feature simplification rather than a foundational architectural improvement.
