Zig project run

[den-mentiei]

Feature request

zig-mode currently exposes zig-run, which creates an executable from the current buffer and runs it immediately.
However, for bigger projects, there is usually a buils.zig with a run step, which could be invoked via zig build run.

It would be nice to have an ability to invoke that project-level run.

Motivation

build.zig is super common and having this improves developer experience, making edit-run-loop shorter.

Details

run step is a custom thing, which is not always available. We can have a defcustom for it with a default value and then users can either configure it in their configs or dir-locals.

We can expose zig-project-run (bound to C-c C-p or something, have no strong preferences).

Background

• zig-run for files with external dependencies #96
• Included the option to call zig build run from the project root. #74 (stale)

Contribution

I can work on a PR for this.
