Bump to v0.5.0 — OS coverage expansion

Reason for minor bump (not patch): expanding the npm wrapper from
two OSes (linux + darwin) to three (linux + darwin + win32) is the
most consequential change since v0.4.0 went out. Every platform that
runs Node can now reach the tool through one consistent install line,
not just the platform-native package manager.

Update version pinning examples in README + README-KO + Home/index.html
from 0.4.2 → 0.5.0 so users copy-paste the current release.
