fix: handle non-semver VERSION in update check (#44)

When running via bun run dev, OPENCODE_VERSION is undefined so VERSION
falls back to "local". getReleaseType would crash on semver.major("local"),
silently killing the update prompt. Now skips semver comparison for local
or non-semver versions and always notifies instead.
