Let Studio install the toolchain

The first launch checks for the Peko toolchain: the compiler, the language server, pekoui, and the per-platform build toolchains. On a new machine none of that is present, so Studio opens its setup screen instead of the editor and streams the install as it runs.

Press Install and wait.

The download is large because it includes a private LLVM and the cross-compilation toolchains. That is what lets the one machine you are sitting at build for all five platforms.

When it finishes, Studio opens the project launcher.

CLI: peko setup. Add --json for newline-delimited progress if you are scripting it. peko check reports what is present without changing anything.

Everything lands in ~/.Peko. Nothing is installed system-wide and no other toolchain on your machine is touched, so removing that directory removes Peko.
