Typedframes brings compile-time column name checks to Pandas and Polars

Typedframes is an open-source Python library that catches DataFrame column name errors at lint time rather than runtime, using type annotations to validate column references before code ever runs. For indie data-tool builders and solo analysts tired of debugging KeyError crashes mid-pipeline, this kind of static safety net has real day-to-day value. It plugs into existing Pandas and Polars workflows without forcing a rewrite.
