Tools group and package

[alexander-yevsyukov]

This PR moves the compiler package under io.spine.tools, and allocates the Spine Compiler artifacts under the io.spine.tools Maven group.

Other notable changes

• io.spine.annotation.Modified is used instead of javax.annotation.Generated because:
  1. Protobuf recently annotates its code with com.google.protobuf.Generated annotation.
  2. We do not generate the whole code, but modify it.
• io.spine.tools.compiler.util.Format was deprecated in favor of io.spine.format.Format.
• Gradle was bumped to 8.14.2.

@alexander-yevsyukov LGTM in general.

There are a few things to address, though:

1. Please update the README.md with the links to this repository. They are now pointing to ProtoData.

2. There are several occasions of ProtoData still mentioned in the docs (cannot comment on the lines, as they aren't changed in this PR):

   • io.spine.tools.compiler.context.Member.kt,
   • io.spine.tools.compiler.ast.TypeExts.kt,
   • io.spine.tools.compiler.plugin.ConfigurationError,
   • io.spine.tools.compiler.render.Renderer.kt,
   • io.spine.tools.compiler.settings.LoadsSettings.kt,
   • io.spine.tools.compiler.settings.SettingsDirectory.kt,
   • io.spine.tools.compiler.settings.WithSettings.kt

And also, io.spine.tools.compiler.plugin.Policy.kt and io.spine.tools.compiler.plugin.View.kt reference the wrong Proto file via .../protodata/... path.

These I have found in Kotlin files. There are many more in .proto files which you can identify by searching for "ProtoData" in case-insensitive way.

@alexander-yevsyukov I only point out these things because I have initially encountered a wrong reference to the .proto file, and then searched for "ProtoData" to check if the problem is big. And there are really about 20-30 spots in which "ProtoData" or "/protodata/" should be changed to their respective counterparts.

We can do that in the following PR anyway.

@alexander-yevsyukov One more thing left here.

@alexander-yevsyukov please see my comment.

Other than that, LGTM.

@alexander-yevsyukov how come the PR merged automatically after it has been approved?

@alexander-yevsyukov FYI, I have just disabled this behavior.

Please take my comment into account next time.
