v0.3.9
Distribution reliability: the prebuilt CLI binary now ships inside npm via platform-specific scoped subpackages (@graphify-sf/cli-<plat>-<arch>) pulled in through optionalDependencies + os/cpu, so npm install makes no network request on the happy path — even on networks that block GitHub Releases. The GitHub download remains a non-fatal last-resort fallback (0.3.8 behaviour preserved).
Python package version bumped to 0.3.9 for lockstep with npm + the tag (no functional Python changes).
See CHANGELOG for details.
