[Hubert Błaszczyk (hub-bla)]

Skiko currently publishes platform-specific JVM runtime artifacts from the same projects that produce the Kotlin libraries. Having these additional publications makes Gradle project dependency mapping ambiguous.

As a result, extension modules such as skiko-graphite and skiko-skottie cannot use a normal api(project(":")) dependency on core. They use compileOnly instead which means the required core dependency is not included in their published metadata and user must declare it manually

This PR moves JVM runtime publications into a dedicated runtime-publications module. The producer projects now only expose their runtime JARs through consumable Gradle configurations while the new module is responsible for publishing them.

Additionally, runtime publications can now declare dependencies on other runtime publications. This allows extension runtimes (skiko-graphite and skiko-skottie) to transitively bring in the matching platform-specific Skiko core runtime.

This is an internal restructuring of the Skiko build. It does not change the artifacts or coordinates used by Skiko consumers.

What changed in this PR

Moves JVM runtime publishing into a dedicated module, separating it from Kotlin library publishing so extensions can declare transitive core dependencies without ambiguous Gradle project mapping.

Changes:

• Adds a runtime-publications module for platform-specific, bundled, and variant-based runtime artifacts.
• Changes Graphite and Skottie core dependencies from compileOnly to api and adds matching core runtime dependencies.
• Exposes producer runtime JARs through consumable configurations and updates publishing and signing wiring.
