TODO: skills & docs

Code Review

This pull request translates docstrings from Chinese to English across several SwanLab API files and introduces a new last parameter to the RangeQuery model to filter scalar metrics by a recent time window (in milliseconds). The CSV streaming parser is updated to support this filtering mode, and validation is added to ensure last is mutually exclusive with start and end parameters. There are no review comments, so no feedback is provided.

Code Review

This pull request increases the default pagination page size from 20 to 100 across various API endpoints, translates and expands several docstrings to English, and removes the artificial random sleep from the pagination helper. It also refactors metric fetching by introducing concurrent batching and CSV downloading via a thread pool, and updates the CLI commands to utilize these new classes. A critical logical issue was identified in swanlab/api/column.py where the auto-pagination query fails to set all=False when filters are present, which would cause the backend to ignore the filters; a code suggestion has been provided to fix this.

Code Review

This pull request increases the default pagination page size from 20 to 100 across several API endpoints, updates and translates docstrings to English, and removes the artificial sleep delay in pagination. It also refactors the metrics querying system to support batching, concurrency, and caching, and introduces a new last parameter to RangeQuery for filtering metrics by a recent time window. In the CLI, commands are updated to use the new Metrics and Summary classes, and redundant checks are cleaned up. The review feedback suggests tracking whether a warning about a missing timestamp column has already been logged during CSV parsing to prevent console flooding and performance degradation on large files.
