fix(npm): read install.js version from package.json (#37)

Single source of truth: install.js now reads VERSION from ./package.json at runtime, so the release workflow's 'npm version $tag' bump propagates correctly. Previously the constant drifted from package.json on every release, causing 'npm install -g stacklit' to silently download an older binary.
