[Headless mode] Revive headless mode

[Hello-zoka]

Description of changes made

Migrated to the newer API for running a headless task. Added proper dependencies, so the grazie module is linked correctly.
Added missed value for AppStarter and adjusted it to the API changes.

Now, the headless-mode branch is in the development state, except for having a headless task.

Testing

You can use such a task:

headless -p "path/to/TestSpark" -Proot="path/to/project/under/test/test_java_maven" -Pfile="path/to/class/under/test/Calc.java" -Pcut="org.example.Calc" -Pcp="paht/to/testproject/test_java_maven/target/classes" -Pjunitv="5" -Pjavahome="java/home/path" -Pllm="GPT-4o" -Ptoken="your token here" -Pprompt="path to prompt" -Pout="path to out dir" -PenableCoverage="true" -Dspace.username="your username" -Dspace.pass="your space password" -Didea.system.path --stacktrace


Headless-mode branch updates, which were done by hand for a better review experience:

• Rebase with development
• Reverting commit "remove headless mode"
• Ktlint fixes for files that are not present in development

Why is a merge request needed

Headless mode has not been working in a single branch since the V2 migration.

What is missing?

• I've faced some problems(not every single run) with running Jacoco for collecting coverage. The reason seems to be with the incorrect project resolve, so the projectContext.cut is null.

• Merge Kotlin for headless PR

• I have checked that I am merging into the correct branch

It seems that some processes are not closed when the headless mode is exited.

When I try to run the tga-pipeline with this branch, the first execution seems to work (I got the message [TestSpark Starter] Test generation failed but it runs). And from the second execution, the gradle task failed with the following error:

FAILURE: Build failed with an exception.

* Where:
Build file '/var/tools/TestSpark/build.gradle.kts' line: 256

* What went wrong:
Could not isolate value org.jetbrains.intellij.platform.gradle.providers.ProductReleasesValueSource$Parameters_Decorated@4848516e of type ProductReleasesValueSource.Parameters

Every time I get an error like Could not move inconsistent immutable workspace, it's because a process is still running and using a file inside the location. I don't know which one yet.

Maybe it's related to [TestSpark Starter] Test generation failed in the first run, I can't see the stacktrace right now.

If you don't think this issue is related to this PR, feel free to ignore it. I'll keep investigating on my own.
