Feature Request: Use the current file in the build step

[IRooc]

Describe the feature It would be a nice feature if the currently active filename could be used in the buildstep. 1 example would be to have an external linter/prettier run through the file.

To Reproduce Example would be:

• quick-lint-js.exe %FILE%

or some other tool you'd like to run on the current file

Additional context Maybe you have a library of scripts that you would like to run individually

Yes!! I would even go slightly further and add a few more "variables" that could be substituted. From the top of my mind being able to have those available to commands would be really helpfull for more generic build commands:

• full name of the current file (so we can have a "build and run current file" build command, very convenient for quick tests)
• folder of the current file (if the command needs to output stuff next to the "built" file)
• name of the file, and maybe name of the file without extension (to name the executable after the file)
• working directory of the command

This will be available in the next nightly and will be released in 0.3.4 soon. Please reopen if you notice issues.

Just leaving this here so people know how to use it, thanks! This code shows the tokens that are used in parsing the command https://github.com/focus-editor/focus/blob/8071628b0ef763fa9a7bf3283555466e01c9a8d4/src/build_system.jai#L516

This is not the full list. There's also BUILD_WORKING_DIR and RUN_WORKING_DIR. The full list is in the release changelog and in the default config examples
