Golang Toolchain Management (Local, Versioned)

Manage multiple Go versions locally using official golang.org/dl launchers and a single symlink switch. No system-wide Go install, no version managers, no environment juggling.

How it works?

• Each Go version is installed as a small launcher binary via golang.org/dl
• The launcher downloads and isolates the actual toolchain in ~/sdk/go<version>/
• A single symlink (~/go/bin/go) determines the active Go version
