`aspire` command startup far too slow

[aradalvand]

aspire's startup performance is far too terribly slow for a modern CLI tool — here's a comparison with dotnet:

2025-06-09.08-10-02.mp4

Host: WSL2/Ubuntu 24.04 x64 (20-core Core i7 14th-gen Intel processor, 32GB of RAM, NVMe storage) — I downloaded the executable from http://aka.ms/dotnet/9.0/daily/aspire-Cli-linux-x64.zip

Gets better after the first time, but even from the second time onward it's too slow.
Consider publishing the CLI program as a NativeAOT binary (which offers substantially better startup perf); or applying whatever optimizations have been applied to dotnet to make it snappy; I haven't checked out the source code, but you might be doing too much work on startup.

We know. It’s still a dotnet tool, not a standalone tool yet. We’re going to native aot it
