Enhanced the Wikipedia plugin manifest with metadata fields. Improved misc/tag-release.sh with argument parsing, error handling, and push option. Refactored misc/update-sdk-schema.sh for better portability, argument parsing, and error checking. Updated tests/async2sync.py to use type annotations, fixed regex for 'await', ensured output directory creation, and improved path handling for compatibility.

Thanks for the PR!

While these are at least potentially reasonable changes, they're also 4 sets of unrelated changes that don't belong in the same change set.

If you'd be willing to split it up into 4 separate PRs, those changes could be reviewed separately (although they may have other more specific concerns that would need to be considered on the individual PRs).
