Migration workflow ------------------

1. Fetch *CHANGES.md* from the repo to identify breaking changes between the versions in question: `https://raw.githubusercontent.com/fedify-dev/fedify/main/CHANGES.md` 2. List every breaking change that affects the user's code range. 3. For each breaking change, show the old API, the new API, and a concrete before/after code snippet. 4. Search the user's codebase for usages of deprecated symbols and suggest the replacement. 5. Note any dependency changes (e.g., vocabulary moved to `@fedify/vocab`, runtime to `@fedify/vocab-runtime`).
