Renames the repo directory and every podpuddle/PODPUDDLE reference across code, config, and docs to podsteadr/PODSTEADR (package names, Docker Compose project/service/volume names, env var names, UI/RSS strings). Existing Docker volume data (uploaded blobs, mediamtx recordings, the server's sqlite DB and its nostr identity key) was migrated to new podsteadr_-prefixed volumes with matching filenames so it isn't orphaned by the rename.
