openai/gpt-chat-latest → A (4:1)

Side A replaces a large, unreliable keystroke-driven autocomplete graph with a much simpler paste-and-go flow, removes the obsolete parser action system, redirects directly to the target subreddit on successful parsing, and adds focused URL parsing tests. Although it deletes a lot of code, the core lasting change is a substantial simplification of architecture and behavior to address reliability, whereas Side B primarily restructures CLI commands, help text, and documentation around renamed interfaces with comparatively limited underlying functionality changes.
