Is there an automation tool for migrating from pkg/errors to %w ?

I am not aware of such a tool. I did it manually in the PRs referenced above (so it's basically done, the issue is mostly for tracking purposes).

for posterity: there's also the possibility of writing a dirty program which parses the source and makes the relevant changes using an AST.
