Add v2-todo.md tracking whole-refactor tasks: v1 data-stack and UI-library
teardown, migrator and schema finalization, removal-slated @deprecated sites,
and release cleanup. Link it from the directory README.
Add an internal record for v2 changes that affect how users use the
app. PR authors drop a fragment .md per change; the release manager
aggregates and translates them into the Chinese user-facing release
note at v2.0.0, then discards the fragments with v2-refactor-temp/.
Also translate v2-refactor-temp/README.md to English and link the new
directory from it.
- Add data-classify tools for data inventory extraction and code generation
- Include consolidated Chinese documentation (README.md)
- Update generated file path references
This temporary directory will be removed after V2 refactor is complete.
