CLI: default zig <path> to be zig run <path> to allow drag-and-drop execution on Windows

[expikr]

On windows, if you drag and drop a file onto an executable, it is equivalent to running <exec file> <dropped file>.

This is particularly useful for the “teach your friend to code” use cases where the quick-start instruction boils down to:

1. Download and extract zig
2. Write your Hello World and drop it onto zig.exe

I know ideally one should teach the “proper way” starting off learning how to use the CLI or IDE, but I think reducing these kinds of minute “gateway friction” really goes a long way in minimizing the initial intimidation factor esp for those who are not yet technically inclined.

Zig being relatively “small” is ideal as a first language so I think there is a great opportunity here to polish some of these trivial details that are typically overlooked in other languages.

in dlang, it has a tool 'rdmd' to call dmd complier and run it, just like a scripting language

IMO if yor're learning zig, should learn the difference between compiled and script

I've already thought a lot about this and decided against it. For the "teach your friend to code" use case, what I think should happen is the VSCode Zig extension should automatically install zig for you and walk you through creating an application. Ideally it would even have a template for gui programming so that new programmers don't have to learn about terminals.
