fix: compensate for inscribed polygon in offset distance

Browse Source 
Polygon chords are always inside the actual arc, making the offset
boundary smaller than intended. Add PushChordTolerance to the offset
distance so the polygon conservatively overestimates, ensuring the
real offset geometry never overlaps stationary parts.
