Subject: [PATCH] perf(sdk): import only the semver functions the ESM loader
 uses

semver.utils.ts imported the semver package root, which loads all 46 of its
files, at startup. It uses seven functions; importing them from their own
modules (semver/functions/*.js, semver/ranges/*.js) loads 23 files, with the
same results.
