Description

As of go v1.24, tools such as golanci-lint can be managed via the mod file and called directly on the go binary via the tool subcommand.

As of v0.31.0 rtk does not handle this command, requiring golangci-lint to be installed on the users's $PATH.

$ go tool golangci-lint run main.go 
main.go:6:7: printf: fmt.Sprintf format %s has arg 9.0 of wrong type float64 (govet)
	i := fmt.Sprintf("hello %s", 9.0)
	    ^

$ rtk go tool golangci-lint run main.go
main.go:6:7: printf: fmt.Sprintf format %s has arg 9.0 of wrong type float64 (govet)
	i := fmt.Sprintf("hello %s", 9.0)
	    ^

Research direction
Investigate how rtk currently handles the `go` command and its subcommands. The issue requires adding support for the 'tool' subcommand, passing arguments correctly to the Go binary. Look at the command dispatch logic, likely in rtk's main module or CLI parsing. Check if there are existing tests for Go command handling.
