Notes

• This is a mechanical deletion refactor: foundational PRs remove a parameter/field, and the PRs above them remove the now-dead call-sites. Individual lower PRs are not expected to build standalone.
• Graphite branch: arayner/SERVER-101422-13-sharding-ddl-catalog
• Buildable checkpoint: No — depends on call-site removals in higher PRs to compile.
