Jean Boussier and Ary Rabelo are on a cleanup spree, removing dead code that would have crashed on contact.

Rails core is decluttering Active Record internals, with Jean Boussier merging a PR to eliminate `QueryCacheRegistry#clear` [1] and Ary Rabelo removing unreachable branches that would raise `NameError` [2]. The Arel fake record also loses its broken `columns_hash` method, which raised `ArgumentError` on any call [3]. For apps managing Vitess tables, a new config `config.active_record.schema_ignored_tables` [4] unifies schema dumping and caching, so you no longer need to set both `SchemaDumper.ignore_tables` and `schema_cache_ignored_tables` separately. Meanwhile, solid_cable gets a clearer naming scheme [5], and lemans adds retry support and Docker integration [6][7]. None of these are breaking, but they signal a tighter codebase for the upcoming Rails release.
