v0.5.0

Download tool@version from the constructed nupkg URL — no version-index round-trip unless that GET is 404.

Exact-version download

A first ndnx stop@2.1.0 now:

1. Resolves PackageBaseAddress from the v3 service index (kept in memory for the process)
2. GETs {base}{id}/{version}/{id}.{version}.nupkg
3. Lists versions only if that GET returns 404

A RID hop (stop → stop.win-x64) reuses the cached service index and the same constructed URL, so index.json is not fetched again.

Unspecified version or @* still lists the feed for latest, same as dnx. An exact version already in the global packages folder is still a cache hit with no network.

Startup time

Cold is empty-cache download → start; cached is start only (tool@version). linux-x64 (WSL2) is SDK 10.0.110; win-x64 is SDK 10.0.303.
