Journey Friction PR Agent

Set up a new bot for me that monitors customer journeys on my website and turns confirmed friction points or errors into draft pull requests. Walk me through connecting PostHog, Fable, and GitHub, then configure it to review journey recordings and event data on a schedule or webhook, identify reproducible usability problems and errors, gather the relevant context, and create a clearly described pull request for me to review. Ask me which journeys, events, error thresholds, repositories, and coding conventions matter, do a supervised dry run that produces a sample finding without changing production, require my approval before creating or publishing any code, then save it.
