Blindly using args[0] misleads users when an env is passed.
Before:
```
==> go build -ldflags=-s -w -X main.version=1.64.8 -X main.commit=8b37f14 -X main.date=2025-03-17T16:54:02Z ./cmd/golangci-lint
brew: command not found: {"SHELL"=>"bash"}
Error: Failure while executing; `\{\"SHELL\"=\>\"bash\"\} /opt/homebrew/Cellar/golangci-lint@1/1.64.8/bin/golangci-lint completion bash` exited with 127. Here's the output:
