Rename the reflected local `Var` field from `name_hint` to `name` and update its typed C++ consumers. Preserve distinct named-node APIs and the Python constructor keyword compatibility path, while making `.name` the sole stored Var property. Upgrade legacy compact JSON records for current and pre-unification Var schemas. Validation: full runtime/compiler build, focused C++ Var copy-helper test, focused Python IR/Relax/TIRx/script tests, Vulkan codegen syntax build, touched-file pre-commit checks, and `git diff --check`.
