Decode the people list from each project's /capabilities and set the /ask person field from a whole-word, case-insensitive name in the question when the caller did not name a person. Match only the routed project's people, so a name from another project does not leak across. Fall back to asker when no name matches. Co-Authored-By: Paperclip <noreply@paperclip.ing>
