post-merge fixes: enum-variant flags, self expansion, mdtest expectations

- sort pep695 typevar-removal iteration and merge rename frames via extend
  (new iter-over-hash-type lint)
- regenerate uv.lock for the merged [dependency-groups]
- accept ci-gate inline snapshots (.pyi->.byi paths, ty->by binary name,
  fork doc urls, 0.0.3 crate versions); rustfmt pass

- pack class-header bools into ClassLiteralFlags (salsa 12-field limit), add
  IS_ENUM_VARIANT so upstream's has_type_params fast path doesn't skip
  variant generic-context inheritance
- expand a payload-enum-bounded Self to its variant union in expand_type so
  match self stays exhaustive under upstream's new coverage analysis
- gate upstream's ~T negation-type syntax and BitAnd runtime probe to
  standard python files
- port covariant-projection write check into attribute_assignment.rs
- rewire based payload-enum split from deleted narrow.rs helpers into
  type_expansion.rs
- update mdtest expectations for fork divergences (covariant Mapping key,
  typeshed typevar names, is_subtype_of moved to ty_extensions._internal)
- dedupe [dependency-groups] in pyproject.toml
- regenerate ty docs (cargo dev generate-all)
