check-metadata-typos

Check metadata files for spelling typos using comprehensive spell checking.

Note: Archived steps and snapshots (defined in dag/archive/.yml) are automatically excluded from checking as they are no longer actively maintained.

IMPORTANT: Check if codespell is installed before attempting to use it. Since codespell is now a dev dependency in the project, it should already be installed, but verify first to avoid reinstalling unnecessarily.

使用 codepell 检查 .meta.yml 和快照 .dvc 文件是否存在拼写错误。当用户提到拼写错误、拼写错误、元数据质量或想要检查元数据文件是否有错误时使用。 来源：owid/etl。
