.detect_case_mismatch

Finds keys that would match if case-insensitive but don't match case-sensitive.

internal

Provides diagnostic tools for understanding and debugging data frame
joins. Analyzes key columns before joining to detect duplicates, mismatches,
encoding issues, and other common problems. Explains unexpected row count
changes and provides safe join wrappers with cardinality enforcement. Concepts
and diagnostics build on tidy data principles as described in Wickham (2014)
