It provides a simple, ergonomic interface for common data operations.

COMMANDS:
  Core:
    headers    Show column names
    count      Count rows
    head       Show first N rows
    tail       Show last N rows
    slice      Extract row range
    reverse    Reverse row order
    behead     Remove header row
    sample     Random sample of rows

  Column operations:
    select     Select columns (supports glob, ranges, negation)
    drop       Drop columns
    rename     Rename columns
    enum       Add row index column

  Row operations:
    filter     Filter rows by expression
    search     Filter rows by regex match
    sort       Sort rows
    dedup      Remove duplicates
    top        Get top N by column

  Transformations:
    map        Add computed columns
    transform  Modify existing columns
    explode    Split column into multiple rows
    implode    Combine rows, join column values
    flatmap    Map returning multiple rows
    pivot      Reshape rows into columns
    transpose  Swap rows and columns

  Aggregation:
    agg        Aggregate values
    groupby    Group and aggregate
    frequency  Count value occurrences
    stats      Show column statistics

  Multi-file:
    cat        Concatenate CSV files
    join       Join two CSV files on key
    merge      Merge sorted CSV files
    split      Split into multiple files
    partition  Split by column value

  Data conversion:
    to         Convert CSV to other formats (json)
    from       Convert other formats to CSV (json)
    shuffle    Randomly reorder rows
    fixlengths Fix ragged CSV files

  Output:
    view       Pretty print as table
    flatten    Display records vertically (alias: f)
    fmt        Format output
