Reject scan --workers below 1 as a usage error (closes #10)

A --workers value of 0 or less used to be quietly raised to 1, so a typo ran the whole scan on one worker with nothing on stderr to say why. scan now refuses it before anything is scanned: one line on stderr and exit 2, like the other usage errors. The clamp in runScan is gone, and README states the rule and the default. Model: opus-5-5
