Generates a plain-language illustrated walkthrough for non-trivial pull
requests at the end of default-workflow. Detects the hosting platform
(GitHub or Azure DevOps) from the git remote, skips trivial PRs with
configurable thresholds, and produces a reviewer-oriented markdown document
that explains the problem, the approach, and the step-by-step implementation
with code snippets, mermaid diagrams, deep links to the diff, and — when GUI
or TUI paths change — embedded screenshots.
Use when: a non-trivial PR has just been opened and an unfamiliar reviewer
needs a clear, complete, jargon-free explanation of what changed and why.
