// #36: every caller (claude.ai connector, gitea's own convention) sends the
// repo identifier as `repo` and issue/PR index as `index`, but the tools
// declare them as `name` and `number`. Unmatched fields zero-valued the path
// segment and produced gitea's misleading /api/swagger 404. parseArgs now
// aliases repo->name and index->number so the idiomatic call works.
