SwiftJWW 1.0.0
First release. Native-Swift, dependency-free reader for the JWW (Jw_cad) binary format + a jww2dxf converter. Core entities: line, arc/circle/ellipse, point, text. Clean-room port of the documented byte layout; validated byte-for-byte against the reference reader on real v7.00 drawings (identical entity counts + bounding boxes).
