v0.3.0

[0.3.0]

Added

• --json flag: print only the final results as a single JSON object (server, connections, duration, and per-stage mbps/bytes/seconds), with no header or live progress.

Changed

• The bar chart now sizes itself to the terminal width instead of a fixed 50 columns, and the header is truncated so it cannot wrap and desync the redraw on narrow terminals.
• When stdout is not a terminal (piped or redirected), the tool no longer rewrites a progress line; it prints just the header and the final per-stage summary.
