Specific wear rate, nominal line contact — from scar depth and width

Archard specific wear rate for a line-contact (pin-on-ring) wear scar, computed from the scar depth and semi scar width, deriving the ring radius algebraically.

The ring-radius formula reproduces the legacy source’s own sign quirk (b²−h² instead of the algebraically-correct b²+h² inverse of c6_3a’s forward relation) verbatim — not corrected here, per this migration’s no-silent-fix rule. See c6_3a for the forward calculator (input ring radius + scar width, output scar depth).
