//! Diagnostic: parse gbx_ue_data_table.bin and dump extracted data tables.
//!
//! Usage:
//!   dump_data_table [path] [filter]             # TSV to stdout (default)
//!   dump_data_table --json [path]                # JSON to stdout
//!   dump_data_table --write-dir DIR [path]       # per-table TSVs to DIR/
