      summary: Rename profile by ID or name
      description: Update a profile's name. Names must be unique within the logical project; during the default-project migration, unscoped profiles and profiles in the org default project are treated as the same project. Duplicate-name conflicts are checked before update but are best-effort because there is no backing unique index. Renaming a profile while a browser session references it by name may prevent that session's changes from saving; prefer renaming when the profile is not in use.
