ratrace import [--curl <command> | --har <file>] -o <output.yaml>

Converts existing requests (curl commands or HAR exports) into RatRace templates.
Useful for integrating with existing workflows.

ratrace report --input results.json --format [html|json] --output report.html

Generates human-readable reports from race test results.

ratrace ratelimit -u <url> -c <concurrency>

Tests if endpoints are vulnerable to concurrent rate limit bypass.
