[3.1.1] - 2025-02-24

Highlights:

• sample: is now a "smart" command that uses the stats cache to validate and make sampling faster.
• With the QSV_STATSCACHE_MODE env var, you can now control the stats cache behavior suite-wide, making sure "smart" commands use it when appropriate.
• luau command's capabilities have been significantly expanded with:
  • New accumulate helper function for aggregating values across rows
  • Optional naming for cumulative helper functions
  • More robust error handling and improved docstrings
  • Enhanced scripting performance with fast-float parsing
  • new Wiki section with examples of using its helper functions
• schema: now does type-aware sorting of enum lists, making JSON Schema enum list customization easier when fine-tuning it for JSON Schema validation with validate.
• lens: adds --freeze-columns option with a default of 1, improving navigation of wide CSVs
• stats: adds --dataset-stats option to explicitly compute dataset-level statistics. Starting with qsv 2.0.0, it was computed automatically to support Datapusher+ and the DRUF workflow, but it was causing confusion with some command-line users.
